Infrastructure bonanza for PVC!

s the nation gears up to the planned investment outlay of a whopping $ 1 trillion on infrastructure during the 12th Five-Year Plan, it promises a plethora of opportunities for several sectors, including Polyvinyl Chloride (PVC). Widely referred to as ‘an infrastructure plastic’, PVC in recent times has been witnessing a surge in its scope of application beyond the traditional territory of construction industry to agricultural and other areas. A quick dipstick reveals that pipes in India account for the largest end-user of PVC followed by other sectors such as calendered products, wires & cables, films & sheets, profiles, footwear and healthcare. However, the application of PVC in large diameter pipes is yet to take off here in a big way as compared to the global scenario. Given this, the need of the hour is focussed technological diversification on the part of PVC players to harness the imminent opportunities from the large diameter pipes segment. From the domestic demand-supply perspective, while PVC demand is likely to soar at a healthy double-digit average annual rate during the 12th Plan, PVC capacity addition in the country is likely to go up albeit marginally during the same period. As a result, the demand-supply gap is projected to more than double from about 800 Kilo Tonne (KT) in 2011-12 to about 1,700 KT in 2016-17 (including paste grade), as per statistics presented in a recent conference. This further leads to the inference of more imports, which should be a wake up call for the policy makers as well as the producers to arrest the looming import dependence well in time.

Eriez’s new PolyMag XRD X-ray visible plastic additives Eriez has introduced new PolyMag XRD plastic additives that impart a high level of X-ray contrast into plastic mouldings in order to safeguard consumers against plastic-contaminated food products. The PolyMag XRD additives help ensure food products contaminated with broken pieces of plastics or rubber do not reach consumers. These impart Xray contrast into food contact plastic articles such as tote bins, paddles, pails, pallets, scoops, scrapper blades, shovels, conveyor buckets and chains, belting, gaskets, grommets, O-rings, and others.

These Food and Drug Administration (FDA)-compliant additives are available in beige coloured pellets having high X-ray contrast properties. The pellet’s co-polymer carrier resin is compatible with a wide range of polymers including polyethylene, polypropylene, thermoplastic elastomer and thermoplastic polyurethane resins. Detectable plastics are most often pigmented blue, which can be accomplished when using PolyMag XRD or the conventional Gray PolyMag Metal Detectable Additives. Typically, the PolyMag XRD additive is included at loadings of 10-20 per cent by the moulder.

New backflush screen changer by KREYENBORG GmbH KREYENBORG GmbH has launched backflush screen changer type K-SWE4K-75-V/RS that boasts of power, performance and precision in one. In the newly redesigned backflush screen changer with proven power backflush technology, 75 per cent of the technology is applied; hence, only one of the four screens is taken out of the production during backflush or screen change. This results in a higher constant melt pressure during screen change and backflush. The new version of the V-Type has higher efficiency of backflush, longer screen life and process, pressure & volume flow constant during backflush, and screen retainers are optimised. This results in a more efficient backflush due to higher backflush pressure capability. The new V-Type shows low melt

volume due to rheologically optimised displacement pistons and flow channels, and hence shorter residence time of the melt. Prior to backflush action, the required backflush melt is stored by a reverse movement of the displacement piston, creating a reservoir. The backflush material is then compressed and discharged for flushing and cleaning the screen. During normal production, this reservoir is filled by the volume of displacement piston, eliminating any points of melt stagnation.

Clear Lam Packaging Inc has created a new film structure made partially from plant-based plastics, which is being used for packaging cheese sticks. The package, which holds individually sealed cheese sticks, is made from a lamination of a 50 per cent plant-based, renewable plastics and an outer layer made from conventional petroleum-based plastics. It is produced from plant-based bioplastics derived from Natureworks’ Ingeo Polylactic Acid (PLA) along with ingredients that enhance its

performance. The material is then laminated to a polyolefin. The material extrudes at lower temperatures than the conventional petroleum-based plastics. On the packaging lines, the new material seals and cuts at speeds that equal or exceed the conventional materials that it is replacing. The new material generates up to 35 per cent less greenhouse gases and uses up to 36 per cent less energy than the conventional petroleum-based material.

Expanding beyond the conventional Courtesy: Promens

otational moulding, also known as rotomoulding, is a recent technology in plastics processing, which has received wide acceptance the world over. With advantages certain to attract manufacturers and users alike, rotomoulding has useful applications in conventional and imaginative product lines. The option to create onepiece, seamless and stress-free plastic products with superior surface finish has arrived. The resultant products can be large or small, in every conceivable shape and of utilitarian & even exotic nature. Rotomoulding offers a definite production and cost advantage over other widely used processes. Rotomoulding is a high-temperature, low-pressure manufacturing method that combines heat and biaxial rotation. Typical moulded parts can include parts such as containers, canoes, tanks, children’s toys, medical and industrial equipment and automobile parts. 38

Modern Plastics & Polymers | May 2012

A unique, globally recognised plastic moulding process, rotomoulding is used to create seamless, stress-free, hollow one-piece products, which can withstand high temperatures and display design versatility. Anwesh Koley takes a closer look at the rotomoulding process and the reasons for its increasing popularity worldwide. Proponents of the rotational moulding process indicate its low production cost and unlimited design possibilities. Offering designers the opportunity to manufacture stressfree parts with uniform wall thickness and complex shapes, rotational moulding is a competitive alternative to blow moulding, thermoforming and plastic injection moulding. Balbir Bhasin, Director, Simplast India Pvt Ltd, says, “The rotomoulding industry in India is a relatively new industry. In the non-water tank area, many companies have entered the road safety, toy and automotive parts segment, but the industry is still dominated by tank manufacturing.” Customers are widespread across the country and an increasing need is felt for rotomoulding in engineering applications in various industries. The quality demanded for water tanks is quite high, so it becomes difficult to shift to a different application. It

produces little waste since the required weight of plastics to produce the part is placed inside the mould. Yet, some critics point towards its longer cycle times, as it involves only one or two cycles per hour, and thus prefer faster manufacturing processes.

Mould preparation The process of mould preparation begins with filling a hollow mould with a pre-determined quantity of polymer powder or resin. This powder can be pre-compounded to the desired colour. More often than not, the powdered resin is Polyethylene (PE), although other compounds such as Polyvinyl Chloride (PVC) and nylons can also be used. The oven is pre-heated by convection, conduction or, in some cases, radiation to a temperature range of 260°C-370°C, depending on the polymer used. When the powder is loaded into the mould, it is closed, locked and loaded into the oven.

Rotomoulding

It is important that the cooling rate be carefully measured because rapid cooling causes the polymer to shrink too fast and warps the part. When it has cooled sufﬁciently to be handled and the polymer can retain its shape, the mould is opened and the part removed. Balbir Bhasin Director, Simplast India Pvt Ltd

Heating and fusion in the mould Inside the oven, the mould is biaxially rotated (ie, rotated around two axes) as the polymer melts and coats the inside of the mould. The rotation speed is slow, less than 20 rotations per minute; the process is not centrifugal. Timing is critical during this phase of the rotational moulding process. “If the mould is kept inside the oven for a long time, the polymer will degrade, and this will reduce its impact strength. If it is inside the oven for very less time, the polymer will not melt completely and not fully coalesce on the mould wall, thus creating large bubbles in the product.”

He elaborates, “We use cross-linking PE, which starts as a thermoplastic, but ends up as a thermosetting plastics during the rotational moulding process. In India, cost plays an important role as, customers are not primarily concerned with the aesthetics of rotomoulded products,” adds Bhasin.

Appropriate cooling of mould After the melting has been consolidated to the desired level and the timing is right, the mould is removed from the oven and cooled. Cooling of the mould is typically done using air, water or sometimes a combination of both. Cooling allows the polymer to solidify to the desired shape and shrink slightly so that it can then be handled by the operator and removed from the mould. The cooling time can typically be measured in tens of minutes. It is during this process that temperature control is required. By systematically regulating the temperature of the mould and the material, there is no need to wait for the preset time to collect the material. “It is important that the cooling rate be carefully measured because rapid cooling causes the polymer to shrink too fast and warps the part. When it has cooled sufficiently to be handled and the polymer can retain its shape, the mould is opened and the part removed,” explains Bhasin. The moulding process can then be repeated by adding the polymer powder to the mould.

Types of moulds Moulds used in the rotational moulding process are typically manufactured from

either stainless steel or aluminium. Although thicker than equivalent stainless steel moulds, aluminium’s thermal conductivity is many times greater than that of steel, and thus the rotational moulding cycle time is not significantly affected. “In India, the quality expectations from rotomoulded products have only recently gone up. Still, if we compare Indian rotomoulded products to similar products available in countries such as the UK and Italy, we lag far behind in terms of design, material grade and rigidity; hence, we have lowquality aluminium moulds available in India,” laments Bhasin. Aluminium moulds are the most common type of mould used in the rotational moulding industry. With cast aluminium moulds, manufacturers can produce complex shapes with intricate detailing in a wide range of sizes – from very small products such as ear bulb syringes to large industrial items like waste water holding tanks. According to manufacturers, a cast aluminium mould is preferred for its characteristics such as heat transfer, malleability, strength, design flexibility and faithful reproduction of the product’s appearance. Gradually, rotomoulders are realising the importance of offering better designs and light-weight products, which fulfill the needs of functionality as well as aesthetics. However, a vibrant capital market, with upcoming infrastructural opportunities and an ever-expanding customer base is expected to benefit the rotomoulding industry, which is fast exploring newer product segments.

In comparison to other moulding processes such as injection or blow moulding, rotomoulding is exceptionally cost-efficient, as the moulds are not subjected to any form of pressure or stress throughout the process. Anwesh Koley delves into various requirements of the rotomoulding industry in terms of raw materials and designing.

otomoulding is often described as one of the most versatile techniques to produce various products. It is a unique process that requires an average polyethylene to perform a variety of tasks. It is important to look at the optimum process conditions for different polyethylene grades and the sensitivity of impact properties to the oven time and temperature. Yuvraj Singh Ahuja, Director, Frontier Polymers Pvt Ltd, says, “Today, people are opting for more modern machinery and the spending power has gone up. But, in India, rotomoulding is still regarded as a water tank manufacturing industry. Every manufacturer is trying to diversify into other verticals such as material handling and road safety. Some other players have found their niche markets in automobiles.” Process conditions become critical for maintaining impact properties, while running multiple types of moulds on one spider or varying from standard process conditions with like moulds. Not all grades of polyethylene with the same 42

melt index and density perform the same. Without proper antioxidant packages, impact strength can vary considerably with process conditions because of small process windows. This can become evident while running multiple moulds simultaneously where mould conductivity, part weight, thickness and arm positions vary, or where oven time and temperature vary between cycles. Rotomoulding is known to yield smooth and seamless moulded parts with precisely uniform wall thickness and fantastic shock absorbing capabilities. Complex outline with excellent surface definition is also possible with this process. The moulds are relatively strong and flexible, as no stress is subjected during the production process. Moreover, reinforced ribs can be designed into any part, in case additional strength is desired. Rotomoulding also offers the option of multi-wall moulding, which can either be left hollow or be foam filled to provide immense strength. Another advantage of the process of rotomoulding is the flexibility to make highly complicated

design, right from stiffening ribs and indentations to different textures.

Raw materials Today, polyethylene is the most commonly used polymer in rotomoulding and makes up for over 90 per cent of a £ 660-million per year strong market. Many designers make polyethylene their primary resin of choice on the basis of its availability, ease of processing and excellent properties. This helps in reducing the upfront cost and gaining a competitive edge in the market. All designers may not see the actual production of the parts, nor are aware of multiple variables involved in processing of polyethylene. “To lower the costs, one can reduce the quantity of materials used, which would mean a product with thinner layer. But, over the years, the improved quality of polymers has enabled us to reduce the overall weight of our products without compromising on the key features of a rotomoulded product. Today, various grades of Low Density Polyethylene (LDPE) are available, which are more product-centric,” adds Ahuja.

Rotomoulding process conditions

Rotomoulded product markets As a manufacturer, it depends on the area of rotomoulded products where the company wants to venture. Today, many companies are opting to produce white water tanks instead of the conventional black ones for various reasons. â&#x20AC;&#x153;We faced few hurdles when we decided to manufacture white water tanks, which were aesthetically pleasing and within the budget of our customers. In a country like India where temperatures can go up to as high as 46Â°C, the water inside a white tank stays relatively cooler,â&#x20AC;? adds Ahuja. In this process, the mould with the raw material inside is rotated at the desired temperatures, and no pressure is applied during the process. Polyethylene is the primary raw material used in this process. We use different densities and material flow mechanisms to achieve the desired results. Rotomoulding is still a localised industry, as the cost of logistics involved in freighting these hollow products becomes quite expensive. We are relatively more economical than the West in terms of manufacturing costs. The Middle East is a key market, besides Australia and New Zealand for Indian rotomoulded products.

of the polyethylene chosen for manufacturing a part. By evaluating resins and the size of the process window, moulders can ensure designers that the nominal impact properties are maintained as designed. The moulder can determine the size and sensitivity of the process window by running different oven times at different oven temperatures and recording the impact strength. By monitoring the inside air temperature during the cycle, moulders can pinpoint the optimum process conditions for different moulds and combine only those having common process windows. This practice will help predict impact properties for parts that experience oven times and temperature outside their normal set points. This will allow the moulder to take additional steps to ensure that proper impact properties still exist. Most importantly, if the designers and moulders choose a rotomoulding resin with a wide process window, it dramatically increases the probability of good impact strength on their welldesigned part. Thus, moulders can reduce costs by allowing flexibility in moulds that can be run together.

moulds are placed on an arm or spider and all are processed at the same oven time. With variations in mould conductivity, part weight and mould position, each mould can experience a different internal maximum air temperature within the same cycle. This can lead to some products having poor impact and others with acceptable impact, even though the parts are processed with the same material & oven conditions. Not all cycles on a rotomoulding machine are consistent because of stuck parts, operator error, variances in external conditions such as cooling water and ambient temperature, extended pauses in the cycle and variances in machine conditions. All these conditions can affect the maximum air temperature in the moulds. Thus, moulders that produce like parts on each cycle may still experience dramatic variances in impact properties if they are on the edge of the process window. Email: anwesh.koley@infomedia18.in

The operational versatility and cost-effectiveness of rotomoulding process make it a preferred technique with manufacturers. A number of factors influence the rotomoulding process, which must be dealt with effectively in order to make it the technique of choice for manufacturing a wide range of products. Ravi Mehra

otomoulding is an extremely versatile and economic process that relies on gravity and heat to produce parts with exceptional strength. The finished result is a stressfree, lightweight and seamless design that is very durable. Various plastic resins are available to use, depending on the product specifications, strength requirements and resistance to other substances required. Materials that may be selected include polyethylene, nylon, polycarbonate, polypropylene, Polyvinyl Chloride (PVC) and custom-formulated compounds. These advantages notwithstanding, the Indian rotomoulding industry still has a lot of areas unexplored. Till recent times, rotomoulding has been looked at as a technology associated primarily with making water tanks. Processors had been wary of venturing into other areas of application, which undermined the process. Even for water tanks, most of the market in India is for tanks smaller than 2,000 litre. This highlights the lack of exploitation of this resourceful process by Indian companies. The process of rotomoulding employs the concept of three Ms and a P – moulds, machinery, materials and product design. Using these, rotomoulding opens a wide range of applications. However, Indian 46

Modern Plastics & Polymers | May 2012

rotomoulders have not been able to achieve higher production with lower costs because they are not aware of its uniqueness. Price is the key driving factor here. Over the past one year, many rotomoulders have shifted to blow moulding as a process to manufacture products similar to those produced by rotomoulding. The design and quality of many rotomoulded products clearly highlight areas that leave a lot to be desired.

Factors affecting fuel efficiency A number of factors affect fuel consumption efficiency in the rotomoulding process: Poor quality and design of the oven’s hot air circulation yields uneven temperature inside the oven. In some ovens, a temperature difference of 100°C inside is not unusual. The oven has hot and cold pockets, which is not a conducive arrangement and adds to fuel consumption. Poor design prevents proper mixing of hot air from the burner and recirculating hot air. Often, the furnace and the oven are not separated and the burner flame hits the mould directly. Lower-capacity burner prolongs the initial heating and processing time. Measuring of temperatures at the wrong places also increases fuel consumption. Processors tend to

measure the temperature of the furnace and not in the oven. The temperature in the oven should be sensed where the hot and cold air are thoroughly mixed and a homogeneous temperature prevails. Otherwise the data measured for controls becomes misleading. Working at lower temperatures reduces fuel efficiency. This is mainly because the oven cannot withstand higher temperatures. Many ovens in India lack the provision for thermal expansion. So, working at elevated temperatures such as 250°C either jams the door or distorts the oven structure, or may lead to cracking of the welded joints. Another key problem area is the quality of circulating air. The number of air change in the oven is less and it can be as high as 18–20 times per minute. Poor understanding of the blowers also causes pressure problems. In some places, circulation is less and pressure is more. The pressure of the air must be designed as per the size and depth of the oven. Poor circulation of hot air may occur in the oven. The air coming out and getting directly sucked at the inlet without reaching every corner of the oven leads to high oven resistance time for moulding.

Production solutions

Poor-quality burners yields 80 per cent low fuel burning efficiency. Thus, almost 20 per cent of fuel energy is lost without being used. Fuel quality makes a difference in fuel consumption. Impure diesel gives lower efficiency. LPG also has a difference in calorific values depending on the source of supply.

Rotomoulders have not looked into the market in terms of applications. If blow moulding has replaced rotomoulding in many key product ranges, it is because they are not keen to offer new products to the market. Hence, to effectively compete, companies must utilise the capabilities and technologies of the rotomoulding process to its full strength.

Roadblocks encountered

The way ahead

The compulsion to offer products that are built-to-a-price has resulted in the industry opting for low levels of manufacturing. This automatically invited other processing techniques such as blow moulding to enter the product areas, which were earlier the forte of rotomoulding. Worldwide, especially in countries like Australia, this process is successfully used to manufacture water tanks in single layers, which offer higher levels of sturdiness while being more attractive and colourful. It is mandatory in many countries to have Ultraviolet (UV) resistance, which is not the case in India.

Moulders must design attractive tanks by using better quality moulds, right material grades and powders, machines with process control capabilities and also invest in learning & training the staff. This will enable production of high-quality, highvalue tanks and other products. Utilising the technology principles listed here, one can reduce material weight, cycle times and produce cost-competitive designs & quality parts. Globally, rotomoulders are successfully producing water tanks with high-quality, single layers, which offer higher levels of sturdiness while being more attractive &

colourful. Large tanks (3,000 litre and above) in attractive, UV-stabilised colours are prevalent. Tanks of size 300â&#x20AC;&#x201C;2,500 litre are also available in attractive colours, shapes & designs, eg, slimline tanks. Many such examples are available, which prove rotomoulded products to be unique and competitive to other processes. Indian rotomoulders have had to contend with a series of challenges in recent times, from high inflation, pressures of a turbulent economy to increase in fuel prices. The weakening of the Indian rupee also means that the import of raw materials becomes costly and mostly small- and medium-scale entrepreneurs have been affected. With such external factors not being within the control of domestic manufacturers, one needs to look towards improving viability by adopting ways for the business to adapt to such changes.

“In India, there is a huge scope for rotomoulding in the automobile sector” …believes Rajendra Shukla, Director, M Plast (India) Ltd. In an exclusive interaction with Anwesh Koley, he explains the various advantages enjoyed by the rotomoulding industry as well as its limitations, which the industry must wake up to. do not feel the threat of blow moulding. We have also been guiding our customers in designing special water tanks, which cannot be made through blow moulding. More than 60 per cent of water tanks are made with the Rock-n-Roll method. The raw material grade available for making water tanks with blow moulding is of higher quality than the conventional raw materials used in rotomoulding. The same strength with lower thickness can be achieved through blow moulding, and this is a cause of concern for rotomoulders.

What is the growth scenario of the rotomoulding industry in India? The Indian rotomoulding industry has been growing at a fast pace for the last five years. Initially, it was dominated by water tank manufacturers, but gradually, rotomoulding companies have entered the automotive, road safety and agricultural applications. Hence, the growth in the non-water tank business is greater than the water tank business. However, recently, we have been witnessing competition from blow moulding, as many rotomoulders are shifting to this process for making water tanks. This has resulted in manufacturers having to look for alternative product ranges where rotomoulding is the only possible manufacturing technique. Large-sized companies are fast moving towards blow moulding to manufacture water tanks, but medium-sized companies are looking for alternatives. Many of them are developing techniques to manufacture water tanks, which cannot be made through blow moulding. At M Plast, we are working on the direct line of rotomoulding so that our customers 48

Modern Plastics & Polymers | May 2012

What are the innovations witnessed by the rotomoulding industry? Innovations have primarily come in terms of temperature measurement. Initially, we used to measure the temperature of the hot air inside the oven when the mould was heated. But, now we can directly measure the mould temperature. Through this process, the quality becomes consistent because we are measuring only the temperature of the mould and the material. This also increases the productivity, as we can measure the exact temperature at which the material melts and is collected from the oven, so that we do not have to wait for the preset time to take the product out. This will also not be influenced by atmospheric pressure differences and seasonal variations.

What is the current technology used in rotomoulding? We are currently using burners that emit less smoke and are energy efficient as well. Many machines run on oil, and manufacturers use Compressed Natural Gas (CNG) to run their machines, which are 100 per cent eco-friendly.

Since every manufacturer is concerned about increasing productivity, temperature control helps in assessing the exact mould time, which increases the output through precise monitoring of the material. Initially, machines would operate at about 250°C, but this figure has gone up to 300-320°C, after temperature monitoring became easier. This helps us to ensure almost 20-25 per cent higher production.

What are other application areas of rotomoulding? Rotomoulding has already entered the automotive sector where manufacturers are providing fuel tanks, air-ducts and mud guards to automotive companies. We manufacture spoilers through rotomoulding, and it has substantial demand. In India, there is a huge scope for rotomoulding in the automobile sector, particularly for heavy vehicles. In terms of innovative techniques, we lag behind European companies, but the technology is fast entering the country and manufacturers have started adapting to the same. With regard to moulds, complicated and high-quality moulds are still not available in India. There are sheetmetalfabricated moulds for products such as water tanks and also cast aluminium & CNC-machined aluminium moulds. At present, no companies in India are producing good-quality cast aluminium moulds. Several manufacturers have entered this field, but quality is still a matter of concern. However, with the number of applications increasing every day, we can expect the levels of quality to go up. Email: anwesh.koley@infomedia18.in

INSIGHT & OUTLOOK: Specialised plastic pipes in construction

Buildin new avenues for

rowth

Plastics is increasingly being brought at the forefront as the leading material for use in the buildings and construction industry. Lionel Alva assesses how plastics is driving the niche market for specialised pipes and profiles extrusion and observing a sea change in construction dynamics and perspectives.

wing to its versatile nature, plastics is finding use in several construction applications such as walls, roofs, plenums, doors, attics, crawlspaces, coolers/freezers and so on. The applications can be varied in nature. High-value thermoplastic pipes such as Polyvinyl Chloride (PVC-U) and polyethylene have been used in construction applications for almost 60 years; hence, their properties and design criteria are well understood. Interestingly, it is only in recent years that significant steps have been taken to improve the competitive position of PVC pipes via material savings. The impetus has mainly been in developing countries, given the critical requirement for potable water and the incentive for water authorities and engineers to accept 56

new pipe technologies. The acceptance of more cost-effective pipe systems is motivated by the fact that no single measure can do more to reduce poverty and disease and to save lives, than the provision of safe water & adequate sanitation. The move to higher design stress and thinner wall pipes would probably have slowed were it not for the advances made in perfecting the in-line production process for Oriented PVC (PVC-O) pipes. The PVC-O pipes made from this process have an exceptional combination of strength and toughness properties, enabling much higher design stresses & material savings.

Design considerations Toughness is an essential requirement if PVC applications have to penetrate the

market, which is currently held almost 100 per cent by steel. Development work involves the following: Properties and consistency of the PVC polymer, particularly, K-value, apparent density, Cold Plasticiser Absorption (CPA) or porosity and thermal stability Var ious impact modifiers, considering pipe storage and outdoor weathering Level of addition of these modifiers Extrusion conditions to optimise processing and pipe toughness Development of a suitable pipe joint Testing procedures to verify quality in terms of pipe strength, toughness and consistency A pipe standard for mining, which had to be devised and accepted by the industry

Specialised plastic pipes in construction

Chlorinated Polyethylene (CPE) impact modifiers were selected as providing the best balance of properties and ease of processing. The first PVC pressure pipes supplied for chilled water contained 12 Parts per Hundred parts of Resin (phr) of modifier, which was subsequently reduced to 10 phr in order to increase long-term strength and was later reduced still further, while maintaining acceptable toughness and a 50-year failure stress of 25 MPa. A special pipe-grade polymer was also developed and close tolerances set for pertinent polymer properties. Higher extrusion temperatures and shear are necessary to achieve correct levels of gelation and develop optimum toughness properties; this leads to improvements in the heat stability of the polymer. Polymer developments undertaken at that time, and which have continued over the years, resulted pipes made of a material – PVC-M – whose critical properties were essential to the later development of higher design stress. “Plastics, especially PVC, has given a new lease of life to the construction industry. The light weight and maintenance-free features of PVC have made it easier to engineer it into buildings and constructions, especially with profile extrusion since it offers flexibility for building and construction in the urban scenario, which was not possible earlier. The longevity of PVC applications in pipes and profiles extrusion is another major advantage since the material is more durable than wood or metal, corrosion free and does not have the problem of termite infestations. It has also helped with the concept of green buildings in the country,” avers Rakesh Dubal, Chief Executive Officer, Aditya Plastics.

Market drivers When it comes to profile extrusion, the development of new structural materials is the focus of several organisations the world over. The objective here is to create new nanocomposites and a system to develop lighter materials for structural applications. The research is largely focussed on creating sections of curtain

walls, which are commonly used for façades of buildings, to replace aluminium and steel. The nanocomposites are expected to provide better design flexibility, weight reduction, ease of maintenance, corrosion resistance, high mechanical performance and good fire behaviour. A Lucintel report has stated that the pent-up demand for composites in construction applications in China has resulted in double-digit growth there, while in North America, construction applications are expected to expand at a rate of 5 per cent per year through 2013. In Europe, growth is likely to average over 6 per cent in the same period. Commercial and industrial construction applications are keeping the overall demand for composites from slumping in Europe and the US. Fibre-Reinforced Plastic (FRP) composites are used in a wide range of applications in construction because of the benefits they provide over conventional building materials. Primary benefits include reduced weight, requiring less supporting structure and excellent resistance to corrosion & rotting, which can significantly reduce the durability of structures built with wood & steel. Less maintenance and repairs mean reduced lifecycle costs. Lighter materials facilitate handling during assembly, reducing installation costs as well as

While there are several concerns when it comes to plastics, it is also important that a key sector that affects lives, such as the construction industry, is also well regulated, and there is a need to establish acceptable standards.

transportation costs. Composites also offer greater design freedom, thus enabling creation of complex shapes.

Building a robust future Construction is one of the largest markets for composites globally. While growth has slowed in regions hit by a decline in residential housing construction, including Europe and North America, China and other regions of Asia are experiencing strong growth in this market. Advances in software and technological innovation will open up new avenues for plastics in the construction industry. Significant challenges have been overcome with structurally strong engineering plastics that can meet or exceed the expectations of their conventional counterparts. While there are several concerns when it comes to plastics, it is important that a key sector that affects lives, such as the construction industry, is also well regulated, and there is a need to establish acceptable standards.

INSIGHT & OUTLOOK: Plastics in road construction

RECYCLING waste for profitability With a booming Asian economy, the road construction industry is looking for new avenues to continue the remarkable cadence of infrastructural development in India. Lionel Alva explores how recycled plastics has revolutionised the road construction industry.

ndustrialisation was the precursor that led to the dawn of a new age of globalisation. In other words, it brought about a remarkable renaissance through the mass production of goods and services. However, despite greatly improving the quality of human lives, it also led to the unprecedented problem of consumer waste that was amassed in large amounts. While the problem of waste can be remedied to a certain degree through conventional methods of filling landfill, incineration and composting, but these methods may not be entirely adequate and could bear long-term consequences for the environment. As the world’s population grows, so is the amount and type of waste being generated. And yet the waste produced today shall remain in the environment for hundreds, or perhaps, thousands of years, creating a grave situation for future generations. It is the creation of nondecaying waste materials, combined with a growing population that has fed the waste disposal crisis. One of the key methods that will help ameliorate the situation is looking for avenues where waste can be recycled into useful products. 58

Modern Plastics & Polymers | May 2012

Building sustainable solutions Research in new and innovative uses of waste materials is continually advancing. Many highway agencies, private organisations and individuals have completed or are in the process of completing various studies and research projects concerning the feasibility, environmental suitability and performance of using recycled products in highway construction. These studies attempt to match the society’s need for safe and economic disposal of waste materials, with the highway industry’s need for better and more cost-effective construction materials. With India’s growing infrastructure woes, plastic waste could be the rare panacea to lend itself as a viable alternative and a long-term solution to the carelessly constructed roads in the country today. Plastics use in road construction goes back a long way. Conventionally, plastics has been used as Polyvinyl Chloride (PVC) or High-Density Polyethylene (HDPE) pipe mat crossings, built by cabling together PVC or HDPE pipes to form plastic mats. Roads constructed with plastics include transition mats that ensure smooth flow of traffic. Besides, it

improves the durability and lifespan of Indian roads that are subjected to large volumes of heavy vehicles and irregular maintenance procedures.

Potential of plastic waste The current research to examine the use of recycled plastics in highway construction is wide and varied. Also the use of polyethylene as an additive to asphaltic concrete is not new. However, two new processes also use recycled plastics as an asphalt cement additive – Novophalt and Polyphalt. Here, the recycled plastics is melted into the form of pellets and added to the asphalt cement at a rate of 4-7 per cent by weight of binder (0.250.50 per cent by weight of total mix). Rasool Khan, Director, K K Plastic Waste Management Pvt Ltd, avers, “When mixed with bitumen, the waste plastics increases the melting point of bitumen and enables the road to retain its flexibility during high friction with traffic volume. This enhances the ability of bitumen to withstand high temperature. Shredded plastic waste acts as a strong binding agent for tar, augmenting the longevity of asphalt. The plastic waste is melted and mixed with

Plastics in road construction

bitumen in a specific ratio. Blending generally takes place at 45.5°C, but after mixing the mixture remains stable even at 55°C. Rigorous laboratory tests have proved that the bituminous concrete mix prepared using the treated bitumen binder meets all specified safety and regulatory criteria.” He continues, “Further, the bituminous mix prepared using the treated binder can withstand adverse soaking conditions under water for a longer duration. The durability of the roads laid out with shredded plastic waste is higher than roads with asphalt with the ordinary mix. The binding property of plastics makes the road last longer and imparts additional strength to withstand greater loads.”

Road to success With increasing emphasis on environmental safety, efficient waste disposal methods are being increasingly sought after where avenues for safe and effective waste disposal are becoming scarce. While currently landfills are

starting to fill up and public health safety concerns are becoming a major source of worry, the cost of waste disposal is becoming an increasingly expensive proposition, and the type of wastes accepted in solid waste landfills is becoming greatly restricted. This is one of the reasons for companies looking at new avenues to find and develop beneficial use of waste. Here, the highway construction industry can effectively use large quantities of diverse materials. The use of waste byproducts in lieu of virgin materials, for instance, can relieve some of the burden associated with disposal and provide an inexpensive and advantageous construction product. Also, the deplorable condition of roads in the country could receive a major facelift through the use of plastics and the several beneficial properties that they possess, thus allowing India to build a strong transport infrastructure that will greatly impact its economy.

“The SPF roofing system can provide significant energy savings” …asserts Piyush Pahuja, Director, Anupam Plastics Industries. As a young entrepreneur providing plastics solutions for the construction industry, he believes that besides energy efficiency, plastics enhances the durability of a structure. In a conversation with Anwesh Koley, he explains the reasons for the growing use of plastics in the construction industry. Elaborate on the use of plastics in the construction industry. The use of plastic composites is fast increasing in the construction industry due to numerous reasons. From the construction of new houses to retrofitting and renovation of commercial buildings, and from hospitals to schools, architects and designers rely on plastics to help maximise energy efficiency, sturdiness and performance. Easy availability of plastics, coupled with various grades that can be obtained for a wide range of applications, has made it the preferred choice for the industry. Besides potentially lightweighting a structure’s environmental footprint, properly installed plastic building products can help reduce energy and maintenance costs, as well as improve aesthetics & safety in the long run.

What are the primary materials used for construction and where do you source these from? We source materials from Malaysia, China and Taiwan. We have Polystyrene (PS), acrylic and polycarbonate sheets. PS is sourced from China and Taiwan, and acrylic from Indonesia. The PS sheets are used in the construction of windows and other partitions where the requirement is for straight applications. It is a solid breakable material that can be used as a substitute for glass and is more brittle than PS. Acrylic cast sheet is primarily used for making novelty items such as boxes. This material is softer, can be bent and is heat resistant. Subsequently, we have polycarbonate sheets, which are 60

Modern Plastics & Polymers | May 2012

The current industry trend of using Spray Polyurethane Foam (SPF) roofing systems ensure a long life, renewable and energy-saving characteristics, as well as their ability to control moisture in buildings. SPF roofing systems are resistant to leaks caused by hail, wind-driven debris and high wind blow-off. Furthermore, the SPF roofing system can provide significant energy savings. SPF eliminates thermal bridging by providing a continuous layer of insulation over existing thermal bridges in the roof deck. Also, SPF roofing systems are coated with light coloured, reflective coating, which reduces the amount of heat transported inside the building through thermal bridges.

unbreakable. These are multi-wall sheets used for making overhead shed. These are hollow, Ultraviolet (UV )-coated sheets with ridges inside the two layers, which blocks sun rays and heat. PS is used as a replacement for glass in many constructions, as it is more rigid than glass. Office buildings, schools and other institutes are fast replacing glass with PS sheets. Factory sites require sheds over vast areas to prevent heat from entering the units; hence, polycarbonate sheets are predominantly used in such cases.

Why is plastics indispensible for the construction industry? If we consider a house, we cannot think of one without a roof. A roof is a symbol of safety, stability, durability and protection from external factors.

How have plastics applications for wall coverings evolved over the years? Used on nearly every type of surface, plastic wall covering has grown in popularity, increasingly serving as a design tool of choice for homeowners. Durable and easy to clean, vinyl products offer the added benefit of longevity. The longevity of vinyl is the reason why it comprises a small fraction of the materials that are disposed in landfills each year. Furthermore, the energy required to manufacture vinyl wall coverings is only half as much as is needed to produce the same amount of an alternative wall covering. Also, the property of polycarbonates to prevent heat from entering as well as its rigidity ensures that it is the material of choice for designers & builders alike.

Indian plastics industry on par with global standards in

construction applications? Recent years have seen an increasing trend of plastics being utilised in construction applications. Lionel Alva examines how quality standards in India are impacting the use of plastics in construction applications, wherein lies tremendous potential opportunities.

When it comes to plastics usage in the construction industry, India is lagging far behind in cost benefits. This is because we depend heavily on oil, and with the rising oil prices, it currently does not make for an economical proposition. Countries like the US, which utilise natural gas for plastics, have a major advantage in the cost. The cost of producing Polyvinyl Chloride (PVC) being higher in India than that in the US puts it at a major disadvantage in terms of core competency. Also, total production capacity of PVC, which is a major construction application, is quite low in the country. There is absolute lack of standardisation for PVC-constructed windows and doors, with little focus on quality. Also, currently, only 7 per cent of PVC is being utilised for construction. This can be much higher. Therefore, a pertinent need is to have associations for enhancing the quality of plastics applications in the construction industry.

Director, Sindhu Group

The infrastructure, mass housing developments, household items such as cables, wires and rotomoulding tanks are driving the growth of the plastics industry. Plastics is increasingly being looked at as a suitable avenue, but this change is taking place quite slowly. The specialty polymers have reinvigorated the plastics industry in the construction segment, and is a great feature to be looked at with myriad possibilities in the time to come. However, there is a major demand-supply discrepancy where domestic supply is limited to 1.2 million units, while the demand is for 9 million units; thus, the government must make efforts to give an impetus to this and relook at the antidumping policy to see a sustainable growth in this sector. Only when the government takes a step in this direction, will better regulations, and hence standardisation of construction applications, be possible. Only after this happens, can manufacturers undertake sustainability initiatives.

In the Indian construction industry, plastics has acquired a somewhat reluctant acceptance, but much needs to be done to change the perspective that plastics is not a very durable material. This change does not seem to be happening soon since the industry has to put in enormous efforts to change the perspective, and thus truly harness the potential of the construction industry. While quality of PVC is improving and people are beginning to accept it as a replacement for metals, especially in drainage systems, where conventionally aluminium pipes were used extensively, this has changed to the point where PVC has become rather ubiquitous due to the unparalleled advantages it offers. PVC has a long lifespan, is corrosion resistant and economical, which is a key factor for the market in India. But, while quality is considerably good, we cannot yet claim to be on par with global standards. And for that to happen, concerted efforts are required from both the industry and the government.

Sumeet Sindhu

Editorial take: Email: lionel.alva@infomedia18.in While the booming construction sector in India offers tremendous opportunities, there is a need for well-defined regulations to enhance what is being perceived as a lack of quality and consistency in plastic products for construction applications.

PVDF resin is the material of choice for Micro-Filtration (MF) and Ultra-Filtration (UF) membranes. PVDF membranes are used in potable and wastewater treatment, blood & protein filtration, medical diagnostics and chemical process filtrations where outstanding chemical resistance is needed. Here are some fundamental steps of manufacturing and applications of these membranes. chemical resistance to chlorine and chlorinated solvents, bromine, hot acids and combinations of chemicals for waste handling. Conventional applications are extruded pipes and injection-moulded valves, fittings & pump parts.

PVDF and Kynarflex® PVDF resins are chemically resistant to a wide range of chemicals. These show good resistance against most acids and acid mixtures, weak bases, halogens, halogenated solvents, hydrocarbons & alcohols. PVDF homopolymers are generally resistant to chemicals up to pH 12, while Kynarflex® PVDF copolymers are resistant to chemicals up to pH 13.5. Many factors affect the chemical resistance of a material, such as exposure time, chemical concentration, extreme temperature and pressure, frequency of temperature & pressure cycling, attrition due to abrasive particles as well as type of mechanical stress imposed. One must consult resin manufacturers and chemical resistance data for PVDF resin before using the recommended grade for an application.

Membrane manufacturing PVDF resins are soluble in various solvents, and these solutions can be used to produce membranes by a Nonsolvent–Induced Phase Separation (NIPS) process. In this process, PVDF solution is added to a non-solvent to form a sheet or hollow fibre that may be supported on a non-woven sheet or braid, respectively, for additional mechanical support. NIPS process typically uses high-molecular-weight PVDF grades (eg, PVDF 761, 761A, HSV-900, 460) to achieve high solution viscosities in the membrane-forming process. In contrast to NIPS process, a recent development is the Thermally Induced Phase Separation (TIPS) process. This process uses thermal energy to melt PVDF, and the lowering of temperature allows solidification. The TIPS process is more frequently used in production of hollow fibres than flat sheet membrane. TIPS processes typically use lowmolecular-weight PVDF grades (eg, 710, 720, 740) for efficient melt extrusion in the membrane-forming process.

Factors affecting membrane manufacturing A common factor in both NIPS and TIPS is the phase separation process

to yield a solid, porous membrane. In NIPS, this means utilising a water bath to coagulate the membrane, while in TIPS, a water bath is typically used to quickly cool the molten PVDF as it is extruded. Specific formulations in both NIPS and TIPS include water-soluble pore-forming additives in specific concentrations that will dissolve in the water bath in either NIPS or TIPS to leave a narrow, well-defined distribution of pores in the membrane structure. This pore structure will define the category of membrane separation [Micro-Filtration (MF) versus Ultra-Filtration (UF)] and the degree of water flux in the separation process.

Applications of PVDF Some major applications of PVDF-based membrane systems are in the four areas of water purification, general industrial purification, food and beverage applications and pharmaceutical industry. In the realm of water purification, PVDF membranes are used as MF and UF pre-filtration for reverse osmosis in seawater desalination and purification of brackish groundwater. PVDF membranes are recognised for their importance in

INSIGHT & OUTLOOK: Mould loading systems

Precise movements for faster changeover A common headache for most medium-to-large moulding shops is managing mould changes quickly and efficiently. While this topic was discussed in the previous edition as an overview, it would be worth looking at from the perspective of mould loading and clamping, more so since this aspect involves the heaviest investments. Y R Anand

he simplest way to move moulds around the factory from the storage area to the machine and back would be by using a pallet truck or an overhead crane depending on the weight and size of the mould. While this is acceptable for smaller mould shops, it becomes a tedious affair for a moulding shop having over 20 moulding machines, 100-150 moulds and frequent short production runs, a scenario typical of automotive and engineering components moulding.

Mould loading and movements For very small moulds of weight up to 500 kg, simple tools are available for supporting the mould via tie bars. For smaller moulds, forklifts are also available with an inbuilt mould change system. But these are generally restricted to moulds of weight less than 2-3 tonne. One such system is based on an electric forklift, which is capable of precise manoeuvring and positioning due to its electric steering.

Its lifting unit also makes mould changing possible on machines of different sizes. Also, the moulds can be put into storage on vertically arranged shelves. For this, electronics provide for smooth and precise lifting and lowering movements. A number of mould loading systems are available in the market today, which make mould movements easier for all sizes. These could be completely independent, electric motor-driven, with adjustable height platforms, which will move anywhere in the factory for moving and loading moulds on the machine. Various systems are available, which move on guide rails and are motorised for easy mould movements. Also available are small to very large moulds weighing 3040 tonne. Such systems demand that the moulding shop layout be planned well in advance to allow guided rail systems to bring the mould to the machines. Most such mould loading tables are equipped with their own controllers and interfaces to ensure that the mould loading is achieved in the fastest way. Further, mould safety interlocks are given due respect while

allowing mould opening and closing to allow these moulds. This can be quite critical with larger moulds.

Mould clamping With regard to mould clamping, it is worth planning ahead to ensure easy changes and clamping. This is a challenge for custom moulders, as the end users often decide the mould sizes & types without planning for the custom moulders. However, there are also numerous captive moulding shops where this aspect is not focussed on. The first step is to standardise the thickness of the backplate. This will allow mechanical clamps to be put in place with a quick-lock mechanism, saving much of mould clamping time. The next step is to make the height or width as standard depending on horizontal or vertical loading, which is the preferred method of loading. This standard dimension should include any insulation plate that is used in many cases. A thoughtful preparation (as the previous job is still running) is crucial for a fast changeover. It is wise to prepare checklists to ensure that nothing (eg, the appropriate hoses & couplings) is missed. A well-organised cart with all required tools and bolts should be available prior to every setup. This means that everything is in place as soon as the machine stops. Nothing needs to be searched for or fetched. This saves a lot of time. There are several ways to quickly clamp the mould to the machine platens. The simplest one is the use of quick clamping elements left permanently on the machine platens in fixed positions. Three other basic types of rapid clamping systems are available â&#x20AC;&#x201C; mechanical, hydraulic and magnetic.

Mould loading systems

All quick clamping systems generally have the advantage of centering the moulds with respect to the machine. In most cases, this will eliminate the need for mould centering rings. This is not only a cost-saving step, but also a matter of convenience. Mechanical systems have limitations of size, but are economical. Hydraulic systems are the time tested and proven systems. But these also require a lot of planning since the backplates and ejector hole patterns have to be well controlled to suit the clamping system dimensions. Magnet plates are quite popular today. Despite being the most expensive solution, these allow considerable flexibility. However, some apprehensions are still popular about the safety of this system, but these are incorrect. This is a totally fail-safe system. Even in case of power failure, the moulds will not fall. The magentism is permanent in nature and, to open the clamp, the poles have to be reversed by using power. If the mould falls down, this can only be attributed to poor

safety features of the manufacturer and not the technology. Most types of mould can be used in these systems, without any modification. If insulation plates are used, one should ensure that the backplate is made of steel. Currently, magentic systems are supplied for even large clamping force machines up to 4,000 T. The larger the machines, the larger will be the number of poles. The magnet plates are fixed to the machine platens. This will result in loss of daylight. But, in general, loss of daylight will remain at the same distance irrespective of mould or clamping size, as good systems will achieve higher retaining force by a larger number of magnet poles retaining the same thickness of magnet plates. The nozzle tip and ejectors must be extended to pass through the magnet plates. Multiple ejectors can be accomodated through, but positions of the ejector cannot be changed subsequently.

Design matters Modern well-designed magnet clamping systems also come with many

advanced features such as display of the magnet clamping force, temperature and other useful information. Some of these can be programmed (by the control pendant) to store the retaining force information for several moulds; hence, programming is not needed for every mould when reused. The most advanced controllers can even predict loss in retaining force due to any reason and give warning to the moulder to check this aspect.

AUTOMATION TRENDS: Processing practices

Automated approach for

seamless operations Rotomoulding has opened up new vistas for the plastics industry, allowing for designs that would not have been possible with conventional manufacturing methods. Lionel Alva assesses how automation and technology innovation have made this one of the most popular plastic product manufacturing processes.

he rotomoulding process is a high-temperature, low-pressure plastics formation process, which uses heat and biaxial rotation to produce hollow, one-piece parts. The inception of the rotomoulding process starts with filling a hollow mould with a specified quantity of powdered resin. Generally, the powdered resin is polyethylene, although other compounds such as polypropylene, Polyvinyl Chloride (PVC) and nylon may also be used. The key aspect is that the nature of materials used in the production process is environment-friendly and fully recyclable. Plastic resin, a roto-machine and advanced tooling are all key components of this process. Significant improvements in equipment and technology, coupled with development of polyethylene and other polymeric powders, have led to numerous applications of rotomoulding in the automotive industry. Automation would enable mitigating various problems such as long manufacturing cycles and high failure rates, making it a formidable process for the manufacturer with unlimited application possibilities. 68

Modern Plastics & Polymers | May 2012

Practical challenges It is imperative to find practical solutions to cycle time reduction within the framework of a forced convection machine. Many attempts have been made previously. The rotomoulding apparatus comprises a heat insulating housing with a bottom half and a top half, which may be disassociated for access to the interior of the housing. The interior of the housing contains a first frame, which may be rocked about a first axis and a second mould-carrying frame, which is attached to the first frame and rotates about a second axis normal to the first axis. The original material used for rotomoulding was PVC, which is probably the second most common material. It can be either liquid or powder and comes in a wide variety of durometers. The free surface flow was modeled by the fluid flow inside a horizontal rotating cylinder. The meshless and Lagrangian Smoothed Particle Hydrodynamics (SPH) method was applied to simulate the flow by using an adapted viscosity expression. The cost of production is the lowest for the entire range of production. A rotomoulding oven is used for forming an object from a mould. The oven includes a

cavity for retaining the mould, a burner for heating the cavity & melting the resin and a device for rocking the mould between -45°C and 45°C from a horizontal plane.

Key design considerations “The impact of automation has been significant on the rotomoulding process. Using a fully PLC-controlled rotomachine, we can achieve 24 cycles in a single day. The time taken to manufacture a single product is not more than 12 minute. The key considerations for moulds are that they should be of thickness less than 2.5 mm, maintain temperature at 260°C, have a good set of burners and variable speed blowers with a good outflow. Temperature control is another key aspect here. Thus far, we have not been able to have complete automation in all our processes, but we are getting there,” avers Nitesh Kapadia, Manager, DKNV Engineering Pvt Ltd. Innovative rotomoulding development to improve cycle times and process efficiency while facilitating greater flexibility in product design & integrity for the SME sector requires the following:

Processing practices

Development of an automated feed system for polymer, additives and coolants direct to the rotating mould at any point in the cycle. This will allow production of multilayer parts for enhanced product performance, fibre-reinforced composites and facilitate automatic & controlled internal mould cooling. Decreasing the processing cycle time by about 30 per cent through automated feeding in the loading, heating, cooling and demoulding cycle. Reduced thermal stress to the polymer will allow use of engineering plastics for value-added applications and improved dimensional stability. Integration of rotational moulding simulation software (RotoSim) with new finite element models, validated experimentally, to quantify variables and control shrinkage, residual stress & warpage, leading to higher quality roto-products. Knowledge-based rotational mould and machine design criteria/guidelines

to accommodate the new universal feed system & optimise processing performance. Apply the new automatic feed system, mould & machine design and knowledge-based processing to enable the use of engineering materials & development of new multilayer, fibre-reinforced & Wood-Polymer Composite (WPC) products, achieving target end-user specifications for value-added applications.

Moulding a better future Automation has allowed for a dramatic reduction in labour costs, energy consumption and ability to mould engineered materials. Automation has enabled the integration of an otherwise anachronistic process into complex manufacturing lines as a highly efficient manufacturing system. Moreover, it is through rotomoulding that manufacturers have adopted to cater to the assorted needs of the market. Email: lionel.alva@infomedia18.in

ENERGY MANAGEMENT: Machiner y design

Optimising the energy quotient With rising energy costs and the influence of climate change, the need to monitor & reduce energy consumption has become more important than ever. This holds true for all industries, including the rotomoulding industry, which is gaining momentum in the country. Avani Jain notes the strategies adopted by manufacturers for ensuring energy efficiency.

he rise in the price of energy and materials is a crucial issue with today’s plastics industry. In order to remain competitive, a business must have an effective energy management process for staying ahead of the competition. All plastics processing industry segments are consciously taking steps for reducing their energy consumption and the gradually evolving rotomoulding industry is not aloof from this. Anand Panchal, Marketing Director, N A Corporation (NAROTO), says, “Initially, the Indian rotomoulding industry was limited to manufacturing water and chemical storage tanks. However, with the advent of new technologies and increasing competition, new applications such as material handing products, waste management & fuel storage were found and the rotomoulding industry developed.” With the growth in the rotomoulding industry segment, concerns about achieving energy efficiency and reducing costs also grew. This led to the development of new machines and technologies.

Defining the concept Rotomoulding is a simple process for manufacturing stress-free, hollow plastic 70

Modern Plastics & Polymers | May 2012

products. It involves slow tumbling, heating and melting of a thermoplastic powder in a biaxially rotating mould to produce seamless, hollow plastic parts. The process is typically used to mould hollow parts, especially those with complex and varied shapes not easily obtained by other processes and is highly energy intensive.

ovens and machinery, along with overall handling of the production process is also paving the way towards achieving energy efficiency and waste reduction. Panchal says, “Rotomoulding involves rotation of a mould filled with polymer in an external oven. The process is highly energy intensive. Thus, good design of the heating chamber can save up to 50 per cent of the energy costs.”

Strategies adopted High rates of power and fuel have forced the industry to become conscious of energy efficiency. The processors adopt various strategies for reducing energy consumption during the rotomoulding process. First, as the quality and properties of a rotationally moulded part are highly affected by the processing temperature, it is important that mould temperature is considered while optimising the process. Second, oil heating and cooling of the mould offers reduced cycle times and a higher thermal efficiency. An important area for design and development concerns heating of oil, which flows around the mould. This design allows close control of heating rates and oil temperature to different areas of the mould, thereby significantly reducing the amount of thermal energy used and the process cycle time. Third, use of good burners,

Design of machines Initially, the trend was to employ old or second hand machines, but now processors have realised the inefficiency costs incurred as a result of this trend. The machinery suppliers are now advocating the use of better technology with increased production lines over controlled consumption. Panchal avers, “To reduce the energy cost, the rotomoulders are adopting energy-efficient machines that ensure reduced heating time, better cooling media, use of better quality raw materials, etc.” He further adds, “Heating chamber (oven) is the heart of the rotomoulding process, so every effort must be made to reduce the cooking time of products. We ensure this by implementing efficiently designed burners and blowers, using better quality insulating media/increased

Machiner y design

size for reducing the resin sintering time and fuel cost per resin weight. Further, Programmable Logic Controller (PLC) system is used for monitoring and controlling the process and maintaining error-free working of the machines consistently. Through these steps, the company has reduced the cooking time from about 5 minute/mm of plastics to 3.5 minute/mm and would further reduce it to 2.5 minute/mm in the future. Our machines are designed especially to minimise cooking time, resulting in reduced energy (fuel/power) consumption.”

As rotomoulders strive to achieve economies of scale while eluding escalating operating costs, efficient technology and green innovations will go a long way in deciding the industry’s future. Panchal avers, “The future trend will focus on minimising the cost of production in terms of energy consumed by improving the oven thermal insulation to reduce heat loss, improve air circulation to reduce resin sintering time, reduce mould cooling time to increase production, use of clamping devices for quicker de-moulding rather than conventional nuts & bolts.”

Future trends

Growth prospects

Energy loss in any industrial process or plant is inevitable, but the economic and environmental impacts must not be taken lightly. Overall energy losses in any process, including rotomoulding, can result from designs that do not incorporate energy-efficient specifications such as heat recovery, operations that run on inefficient methods and a poor maintenance programme.

The Indian rotomoulding industry is currently at an exciting crossroads, with growth and expansion in every direction. Amid this bright growth prospects, energy efficiency measure can provide a further boost to the industry. Already companies are making conscious efforts for conserving energy, and it seems that these initiatives will intensify in the future. Email: avani.jain@infomedia18.in

POLICIES & REGULATIONS: Anti-dumping duty on Chinese plastics machiner y

Deciphering the

merits and

demerits

The opinion on the anti-dumping duty imposed by the Indian government on Chinese plastics machinery still remains divided. However, what cannot be denied is the implication of trade ties between the two countries will attract the attention of the international fraternity. Anwesh Koley explores the various propositions spurred by this decision.

he major concern for plastics machinery manufacturers in India is the advent of Chinese machinery at substantially lower prices. The industry had been urging the government to take steps to prevent Chinese machinery suppliers from exporting their machines to India. Finally, in 2009, the Indian Government levied an anti-dumping duty of 223 per cent on imports of Chinese injection moulding machines, justifying that these products flooding the Indian market are affecting the country’s manufacturers’ profitability and causing damage to marketshare.

Implications of the ban The Finance Ministry had imposed definitive anti-dumping duty on imports of certain plastics processing or injection moulding machines from China. The levy was to be in force for five years from May 12, 2009, the date on which the provisional anti-dumping duty was imposed. The specified percentage is in the range of 60-174 per cent, depending on 72

Modern Plastics & Polymers | May 2012

the producer. Based on a petition filed by a Chennai-based machinery manufacturer, the designated authority in the Commerce Ministry had, in 2008, initiated antidumping investigations on imports of plastics processing machines from China. The Revenue Department had specified that the anti-dumping duty would be a percentage of the Cost, Insurance and Freight (CIF) value of imports. However, some machines were excluded from the levy – blow moulding, vertical injection moulding, all-electric injection moulding, multicolour/multimould & rotary injection moulding machine for making footwear. While machinery manufacturers have since then seen favourable times, plastics processors fear that their margins will be hit by 20-25 per cent due to the antidumping duty on imports of certain plastics processing or injection moulding machines from China. Indian machines cost at least 25 per cent more than Chinese machines. While the price of machinery varies with size, quality and degree of automation, on an average, Chinese machines cost between

` 5 lakh and ` 10 crore. Machinery and moulds account for nearly 70 per cent of the cost of setting up a plastics processing business. Indian customs levies on Chinese imports of tariff margin amount will be based on final determination of the dumping case, to make adjustments.

Pros and cons There are more than 5,000 injection moulding units across the country, of which over 50 per cent are in the smalland medium-sized category. India’s net polymer capacity is about 6 Million Tonne Per Annum (MTPA), with Gujarat accounting for nearly 60 per cent of the net production. The net size of the sector is ` 70,000-100,000 crore. Praveen Sharma, Proprietor, Hinds Machineries, says, “The demand for Indian made machinery has gone up after the anti-dumping duty was levied, and many small & mid-sized companies have gone ahead with their expansion plans.” If anti-dumping duty remains in vogue for long, there is a concern that Indian

Anti-dumping duty on Chinese plastics machiner y

machine manufacturers will try to get much higher prices than the current prices, as there is no global competitor. There is also a concern that Indian machine manufacturers can never meet the dispatch target because of their way of working and infrastructure; this is a major reason that the clients in India opt for Chinese machines. But, this issue can be addressed. Domestic machinery manufacturers are in favour of the anti-dumping duty. â&#x20AC;&#x153;We have to compete with Chinese products on the basis of price, which becomes a setback in the initial stages. The financial and fiscal support provided by the Chinese government to its manufacturers cannot be compared to our duty structure,â&#x20AC;? says Sharma. While cost is an area where Chinese companies score over Indian machinery, quality is the stronghold of Indian manufacturers in the global market.

matters such as imports might be a cause of concern in the future, as both countries boast of a booming plastics industry. The All India Plastics Manufacturers Association statistics show that by 2012, India is expected to become the third

largest plastics market in the world after the US and China. Hence, an economic deadlock between the two markets may not be in the best interests of the global market. Email: anwesh.koley@infomedia18.in

STRATEGY: Supply chain management

Ensuring efﬁcient polymer transit With a rich supply of petroleum derivatives and other raw materials, India has become home to leading brands in the global polymers business. Thus, it is important to understand the issues vexing the polymer supply chain in the country. Avani Jain takes a closer look at the special requirements of the polymer supply chain across India.

he primary growth driver for the polymer industry in India is surplus domestic demand, given that India’s current per capita consumption of plastics is only 6 kg as against the global average of 50 kg. Further, the easy availability of polymers has played a pivotal role in boosting the plastics processing industry in India. The production capacity of major suppliers of polymers in India is 4.8 Million Metric Tonne (MMT). Among other reasons for the flourishing polymers sector is the steady growth in industries such as organised retail, agriculture, infrastructure, automotives and pharmaceuticals. Having said that, India is slowly becoming the polymer hub and is responsible for the good growth of the plastics industry in the country. It is thus important to ascertain the requirements of the polymer supply chain across the country in order to ensure effective supply chain management. This fact along with various others can further define the growth of the plastics industry in the country. M M Biswal, Business Head-Polymers, Loxim Industries Ltd, says, “There are a large number of resin and polymer compound manufacturers in the country. The need of the hour is effective polymer supply chain management to ensure that 74

Modern Plastics & Polymers | May 2012

the raw materials and finished goods reach the customers in good shape and on time. Much has been done for this, but certain issues need to be dealt with to make the process more effective.”

The concept A typical polymer supply chain network includes multiple plants, large number of storage terminals, customers and consignment locations as well as complex distribution requirements. In simple terms, it means ensuring that the raw materials, ie, polymer compounds or resins from the manufacturers reach the customers – the plastics processors – safely and on proper time.

Challenges to overcome No doubt good infrastructure facilities including good roads are important for driving effective polymer supply chain management in the country, yet there are other issues that need to be focussed on in order to further give a boost to the Indian polymer industry. Biswal details, “One of the major problems faced in the polymer supply chain across the country is the way materials are handled during transportation. The problem starts right when the polymers or resins are loaded onto the truck. The polymers are generally packed in 25-kg bags, as they are easy to handle. These bags are manually loaded

and unloaded in the truck, which means that they can easily get damaged during the process due to unskilled labour performing the task. Thus, due to rough handling of polymers, the bags get torn while loading and unloading, the seal breaks and the material is left open in the trucks.” He adds, “Polymers are spoiled easily due to moisture and water. Therefore, extra care is needed during their transportation, but the trucks are such that in rainy season, water percolates into the vehicle and the polymers are spoiled. Further, there are high chances of material getting lost during the shipment.” Commenting on other problems related to different taxes, Biswal says, “The different types of taxes such as Octroi levied by the different states, the availability of polymer compounds during that time, etc, also affect the polymer supply chain. Some states charge Octroi on goods and that adds to the cost of the customer. Thankfully, the state in which we are operating, ie, Gujarat, the government does not charge Octroi. Thus, the polymers are not costly in Gujarat. Further, Gujarat is well connected through good roads and ports, and hence no major difficulty is faced during transportation.”

Supply chain management

The need of the hour is effective polymer supply chain management to ensure that the raw materials and ﬁnished goods reach the customers in good shape & on time. Much has been done for this, but certain issues need to be dealt with to make the process more effective. M M Biswal Business Head-Polymers, Loxim Industries Ltd transportation is a key issue and demands improvement. One should ensure that the material is safe and in good condition, till it reaches the plastics processors. Biswal notes, “For that, the suppliers or distributors (in major cases) need to take various steps. First, the labour force needs to be educated and trained so that the manual handling process can be refined. The latest material handling techniques must be employed to ensure minimum manual handling. The suppliers or distributors should store the polymers bags appropriately in their godowns or warehouses; the bags filled with polymer compounds should be stored on wooden pallets and not stacked against walls. Further, the bags should not be stacked one over the other, as this also spoils the materials inside. Before transportation, the supplier must ascertain that the bags are not torn while loading in the trucks, as this may also spoil the product during transportation.” These are some of the measures that can help in effective management of polymer supply chain in the country. These steps should be undertaken by the suppliers and distributors to ensure product safety during transportation of the polymers.

Future prospects As India’s growth story continues in every sphere of the economy, the phenomenal strides taken by the petrochemicals industry seem to be signaling brighter prospects for the specialty polymers and high-performance plastics business. The plastics processing sector in India is worth ` 1.5 lakh crore and is bound to grow further. Due to the good availability of polymers in the country, today, it has become a trend for multinational companies in the plastics business segment to establish manufacturing bases in India. If the aforesaid problems attached with the polymer supply chain are overcome, then there will be no looking back for the Indian plastics industry.

TIPS & TRICKS: Auxiliar y equipment

Selecting the right combination for better productivity Auxiliary equipment for the plastics industry include granulators, gravimetric and volumetric blenders, vacuum & pressure loaders, railcar unloaders, metal separators, dryers, chillers, recycling systems and so on. Anwesh Koley enlists various pointers to consider while selecting the right combination of auxiliary equipment for the plastics machinery. Anwesh Koley

anufacturers of auxiliary equipment are responding to plastics processors’ demands for upstream and downstream machinery that can help

them reduce costs and stay competitive in the global market. Loaders and blenders provide more accuracy and efficiency for reduced waste and improved quality of parts. Higher performance ancillary equipment use less energy and provide cost savings.

Increased efficiencies are being witnessed across the entire range of auxiliaries, contributing to profitability in plastics processing. Energy savers for granulators are the latest developments witnessed by the industry. Email: anwesh.koley@infomedia18.in

Following are some of the pointers for selecting the right combination of auxiliary equipment for plastics machinery:

Moisture content in plastics adversely affects the quality of moulding. Excessive moisture in resins leads to products with unacceptable sturdiness, silver streaks and holes. Drying primarily serves to remove moisture from resins to prevent decline in the quality of moulded plastics. Temperature increase is also used to enhance the plasticity during moulding.

Vacuum thermal conduction is another important feature, as it shortens drying time by creating a vacuum condition. Conduction fins increase the surface area and ensure that all materials in the hopper can be heated simultaneously. Because it does not use hot air, exhaust hot air is not emitted. Initial functionality is maintained even without replacement of absorbent materials.

A low-speed granulator, which can be cleaned safely and thoroughly in a single step, enhances access for cleaning. Enhanced reliability within the granulator can be achieved through reducing shaft stress and eliminating difficult adjustment through double bearing. This extends the lifespan of bearing and makes the exchange of blades & bearing easier.

Air circulation in the rotor affects the absorption in the dryer. The rotor is made of three zones – dehumidifying (absorbs air moisture charged into the hopper dryer), regeneration (heats moisture absorbed to evaporate it, regenerating honeycomb rotor) and cooling (cools the honeycomb rotor to an optimal temperature). These zones enable the honeycomb rotor to provide a stable low dew point of -40°C.

Mould temperature controller provides stable temperature and better safety. It provides a high-precision display temperature, which is accurate up to 0.1°C. An additional memory function can save two different temperatures for easy alteration. A reliable heater control circuit uses SSR (non-contact relay) that enables the shunt-coil breaker to automatically shut down power upon excessive heating.

A water-cooled mould cooling and heating unit that combines mould chiller & mould temperature controller into a single unit can support a wide range of temperature of 10°C-90°C. A large tank enhances the precision at medium temperature and increases performance through a larger flow rate and high-pressure pump, which ensures stable cooling of complicated mould structures as well.

EVENT PREVIEW: Plastivision Arabia 2012

Opening avenues for profitable partnerships Feedstock availability and logistics convenience are among the leading factors that are attracting the Indian business fraternity to the United Arab Emirates (UAE). Looking at this trend, Plastivision Arabia 2012 will strengthen the export avenues for the surging Indian plastics industry into the Middle East. Annabel Dsouza

he Indian plastics industry has taken great strides owing to a rapidly expanding application spectrum and per capita consumption of commodity plastics and engineering polymers. Although the Indian market is primarily driven by domestic demand, Indian entrepreneurs are also exploring foreign shores for business growth and expansion. In keeping with the Indian industry’s advancements in polymer technology, processing machinery, expertise and cost-effective manufacturing, Plastivision Arabia 2012 will open enormous opportunities not only for established players, but also for

small and medium enterprises in the plastics processing sector. Ajay Desai, Chairman, Plastivision Arabia 2012, says, “The UAE plastics industry is projected to grow by 20 per cent year-on-year backed by cheap and easily available feedstock as well as the regional governments’ focus on economic diversification. This presents huge opportunities for Indian manufacturers and investors. The Gulf region, including neighbouring countries such as Iran and Iraq, boasts of the large amounts of the world’s oil & gas reserves. The UAE itself holds the world’s sixth largest proven oil reserves of 98 billion barrels and seventh largest gas reserves of 215 trillion cubic feet. Going by this data, there will never be a

shortage of raw materials for the plastics and petrochemicals industry.”

Strategic advantages During the last decade, the Middle East has emerged as an important player in the global market owing to the twin benefits of low prices of raw material and feedstock as well as proximity to the highly lucrative Asian market. As a rapidly growing region, the Middle East offers an excellent opportunity for companies in plastics and petrochemical processing. The rationale for the lower rates of feedstock is that it is a natural by-product in upstream operations, and hence involves minimal cost of production. This cheap and assured supply provides a significant competitive

advantage to the Gulf players visà-vis their global competitors who procure feedstock at market rates. These cost advantages, coupled with increasing environmental regulation of petrochemicals companies in the West and the rising margin pressure across the world, offer a congenial environment for growth of the petrochemicals industry in the Gulf. UAE is a country strategically linked to high-growth markets such as India and China, apart from several other emerging markets in Africa and the Middle East. This advantage reduces transportation costs in comparison to any South East Asian country or Europe. Plastivision Arabia 2012 will be a significant and comprehensive sourcing platform for raw materials, primary processing and auxiliary equipment, machinery and related products & services. The show is expected to contribute to an exponentially growing plastics industry owing to the twin benefits of abundant availability of raw materials and low feedstock prices in the region. Desai avers, “Indian machinery suppliers are best placed to effectively tap the fast-expanding plastics and petrochemicals sector in the UAE as well as the adjacent regions, owing to factors such as logistical advantage due to geographic proximity, excellent trade & cultural ties, and the unique demographic benefit of trading with a strong Indianorigin business community. Proximity of UAE to India will be a great boon to the manufacturing sector of both regions. With just over three hours of flying time between the Gulf Cooperation Council (GCC) and major cities of India, the cost of transportation and ease of travel

for technicians to install & maintain machines is cost-effective as compared to that in any part of the world.”

Banking on people power The traditionally close and friendly India–UAE bilateral relationship has evolved into a significant partnership in the economic and commercial sphere. Indians have emerged as important investors in the UAE and India has become an important export destination for UAE-manufactured goods. Apart from manufacturing, the two nations have been cooperating on several fronts such as scientific research, defence technology, cultural exchange, among others. UAE is home to an Indian expatriate community of over 1.75 million – the largest expatriate community in the UAE. The Indian community has played a major role in the economic development of the UAE. The economic boom in the UAE has created a huge demand for skilled and

Key highlights of UAE Trade hub of the Middle East Major polymer processing centre Gateway to GCC and African countries Modern ports and logistics facilities Free trade zones Tax-free environment Availability of highly skilled workforce Favourable labour laws Proximity to major consumer base Large hydrocarbon resources

semi-skilled professionals from India. Desai adds, “A major chunk of the 1.7-million Indian population in the UAE involves qualified technical personnel and business professionals engaged in different sectors. The majority of the workforce in the UAE constitutes Indians, and this will help create a unique synergy between both the sides in terms of coordination, cooperation and communication in situations that might arise due to expansions, machinery upgrades and maintenance. Since Indians also hold important positions in major UAEbased companies, their presence in various segments of the petrochemicals and plastics industry is encouraging. Indian investors’ attention in the UAE will play a significant role in the growth and exposure of the region’s plastics industry.”

Strengthening the ties According to the Ministry of Commerce and Industry, Government of India, the data for the 2010-11 fiscal year shows that exports and imports between the two countries totaled $ 67 billion, with exports amounting to over $ 34 billion and imports coming in at just under $ 33 billion. With huge volume demand pressures on the local manufacturing f raternity, the region is becoming the focus of international polymer producers and converters. This offers immense growth potential for the regional downstream industry as well as the international plastics materials and machinery expertise. Desai c on c l u d e s , “Indian manufacturers can also leverage on the flourishing trade ties, with the UAE being the top trading partner of India. As UAE is the commercial and regional re-export hub, Indian plastics machinery suppliers can also explore the rest of the region, with the total number of Indians working and living in the Gulf standing at over six million, and the India–GCC trade accounting for over $ 130 billion in 2010-11.” Email: lionel.alva@infomedia18.in

EVENT REPORT: Vinyl India-2012

Capitalising on infrastructure growth The stage was set for Vinyl India-2012, now in its second edition, which allowed producers and processors to explore opportunities and form partnerships on a unique platform where global giants from the industry could interact with their Indian counterparts, thereby establishing a formidable alliance. Lionel Alva

he illustrious ascent of the Indian polymer industry has been a silent contributor of sorts to the shimmering spectacle of India’s success story as being among the fastest growing markets the world over. It is no secret that the polymer industry does not really get its due despite being an inseparable part of our lives today, as is apparent from its ubiquitous presence in almost every application. This is largely owing to significant innovations in polymers that have opened up new vistas for potential applications that were not considered earlier as being even remotely possible. Vinyl India-2012, recently held in Mumbai, was the second international vinyl conference organised by Chemicals

and Petrochemicals Manufacturers’ Association (CPMA) and Elite Plus Business Services Pvt Ltd. The conference was attended by more than 500 delegates from over 250 companies and 20 countries. The conference saw participation of over 30 eminent speakers from India and overseas. The two-day action-packed event included discussions on Indian and global Polyvinyl Chloride (PVC) industry, feedstock to polymers, machinery, compounding & processing, health safety & environment, PVC profiles and Oriented PVC (O-PVC), which is an emerging technology for high-quality pipes. The major attractions of the twoday event were a panel discussion on the Indian PVC industry and a Chinese delegation. The organisers also presented ‘Life Time Achievement Awards’ to three eminent veterans of the PVC industry

Driving the need for regulations Valued at over ` 20,000 crore, the vinyl industry in India is a force to reckon with and consists of five major producers and over 600 processors engaged in making consumer and industrial products. Vinyl India-2012 provided a strong platform for the industry to build closer ties, examine key areas of concern and establish major business partnerships, further accelerating the growth and development of this vibrant sector. PVC producers and processors equally shared the concern for the need for high quality standards in India, which often takes a back seat and low cost becomes priority. Chlorinated PVC (C-PVC) is an emerging application in India for hot and cold water in plumbing & industrial applications. With India accounting for a sizeable share of global C-PVC, it is another game-changing application that grew by 45 per cent last year. The conference brought out clearly that the pipe sector would undergo structural changes in the next 3-4 years, with preference for quality pipes over low cost. “There is an elaborate focus on the construction industry and much needs to be done to change the perspective. Today, most metallic applications are being replaced with PVC, and although PVC quality is improving steadily, it is still not on par with the international standards due to the absence of industry regulations. The industry has

a promising future, since from here it can only get better,â&#x20AC;? observed Sumeet Sindhu, Director, Sindhu Group. The occasion also witnessed the launch of Indian Plastic Pipe Academy (IPPA). IPPA is envisioned to be a nodal agency and guide the user segment for the use of optimum quality products. Hopefully, this will go a long way in furthering the growth of the industry.

Focus on sustainability PVC consumption in India has grown

over 10 per cent per annum in the past; moreover, future projections indicate double-digit growth. At present, PVC consumption in India is 2 Million Metric Tonne (MMT) per year, with infrastructure and housing sector being the key drivers of growth. Further, the 12th Plan projection of the Government of India calls for increasing the share of manufacturing in the Gross Domestic Product (GDP) from 18 per cent to 25 per cent, which is an indication of the growth potential of the PVC industry. With investment all set to double at

$ 1025 billion in the 12th Plan from $ 514 billion in the 11th Plan, this depicts the potential for plastics applications in the construction industry. The average domestic demand is 12.75 MMT in 2012, with exports at 4.2 MMT. While consolidation of growth opportunities was the key area of discussion, there was a heightened emphasis on sustainability where the speakers highlighted the need for integrated solutions, including the supply chain, value drivers and end-user segments.

BOOK REVIEW

Polyelectrolytes and Polyzwitterions Editor : Lowe & McCormik Price : ` 7,940

Controlled / Living Radical Polymerization Editor : Krzysztof Matyjaszewski Price : ` 11,155

Polymers or macromolecules, which resemble synthetic analogues of fundamental building blocks of life, such as proteins, DNA and certain carbohydrates, are of interest to polymer chemists. Polyelectrolytes and polyzwitterions are such synthetic analogues that find applications in oil recovery, cosmetics, paper making, stabilisers in emulsion formulations, drug delivery vehicles, contact lenses & coating for blood filtration devices. Polyelectrolytes – often called polysalts – display properties of salts and high-molecular-weight compounds in aqueous solutions. Many biological molecules such as proteins and DNA are polyelectrolytes. Polyzwitterions are polysalts that are neutral molecules having positive and negative charges. Polybetains are electrolytes with positive and negative functional groups and are a subclass of Polyzwitterions. The book mentions advancements in Controlled Radical Polymerisation by using techniques such as Stable Free Radical Polymerisation (SFRP), Atom Transfer Polymerisation (ATRP) and Reversible Addition Fragmentation Polymerisation (RAFT). These techniques are used for creating new molecules in biomedical applications, personal care, mining and oil field chemical formulations. The book is a part of ACS Symposium Series of American Chemical Society. This series publishes timely, original research and review papers from ACS-sponsored symposia based on current scientific research in Chemistry.

This volume of Controlled/Living Radical Polymerization comprises topical reviews and specialist contributions presented at the ACS symposium in 2005. The symposium was supported by all leading chemical companies of the world who are engaged in polymer research. This shows the interest in this new field that has emerged in the last two decades. Living polymerisation is a method of synthesising block copolymers, which became popular in the last two decades. Here, a polymer can be synthesised in stages, with each stage containing a different type of monomer with predetermined molar mass and control over end groups. Since polymerisation is carried out with precise control over molecular architecture, the process is called Controlled Polymerisation (CRP). The techniques used are Stable Free Radical Polymerisation (SFRP), Atom Transfer Polymerisation (ATRP) and Reversible Addition Fragmentation Polymerisation (RAFT). These techniques have been developed in the last decade and find applications in commercial production of many new materials. Polymers made from such techniques are used as sealants, coatings and hybrid nanocomposites to improve lubrication and prevent corrosion as well as biomedical applications such as controlled drug release and drug targeting. The book is meant for researchers in the field of CRP.

Air-cooled compressor

Co-extrusion system

A unique range of air-cooled compressors is offered for industries that demand oilfree air at their application point. The non-lubricated compressor offers advantages of low energy consumption and low running costs. The air-cooled design eliminates the need for water cooling systems, thereby saving industrial water costs. Twostage air-cooled aftercooler has a 0.25 kW single-phase motor driving a cooling fan. This eliminates the need for cooling towers, water circulation pumps and the associated piping, thus reducing the initial investment. This also reduces the installed power.

This is a complete air-cooled blown-film co-extrusion system up to 11-layers for the most demanding food, medical and industrial packaging applications. The barrier film line is configured with the legendary streamlined co-extrusion die (SCD) either in its conventional configuration with air-gap temperature isolation between modules or in its more recent compact FlexSTACK configuration. Superior thickness uniformity is achieved with the I-Flex auto gauge control system, while unsurpassed roll quality with any type of film is attained with the FlexWIN gap turret winders with linear lay-on roll.
