At K last month, more than a few exhibitors cited North America’s shale gas phenomenon as a key factor that has the potential to overshadow Europe’s competitiveness in the global race. The good news is that we’re by no means stuck in the stalls, if overall K Show opinion is to be believed; markets and demand, it seems, remain strong in Europe’s plastics sector.

We’ve known for some time now that Europe could hold great potential for self-sufficiency if shale gas is tapped into. Would our chemical and processing industries also gain a noticeable competitive edge if we had access to local, plentiful resources for years to come?

In industry, there are fears that we may be missing a trick.

According to the EC’s recent report concluding its public consultation, which bears the (not-too-subtle) title of “Unconventional fossil fuels (e.g. shale gas) in Europe”, more than 50% of individual respondents argued that shale gas could enhance Europe’s competitiveness, and could also lead to increases in technical innovation. On the latter point, 80% of European academic institutions agree, as do roughly 80% of national authorities.

It seems pretty clear that the majority of voices support a European exploration into shale gas, in the name of competitiveness and innovation.

The EC report also explored the factors restricting further exploration in shale gas, using a survey that included 18 potential issues, such as impact on water, air and soil quality, climate risks and biodiversity. But these very valid concerns were overshadowed by the overwhelming response: quite simply, ‘lack of public acceptance’.

This frustratingly vague answer might be explained by yet more EC stats, which show that before exploration goes ahead, both the public and national authorities would like to see the establishment of an information exchange, as well as guidance on best practice – so this, if the EC is to be believed, is what stands in the way of shale gas exploration. And the good news is, it seems like such measures are already under way.

If this goal is achieved, the final obstacle, which will be particularly prevalent in plastics, comes from a conflict of interests. How can European society, which projects a growing dependence on bio-resources and renewable energy justify simply reverting to non-renewable quantities as soon as they become available? Doesn’t it fly in the face of the fervent research and funding currently taking place to secure a sustainable future?

cover story

Innovation in Polymers ImerPlast™ is designed to help users achieve bottom line savings by enabling the use of recycled polymers in value-added applications, such as pipes and geomembranes.

Post-consumer, mixedcolour, mixed-polyolefin waste is currently widely available and has few applications. Phase separation caused by incompatibilities between HDPE, PP and PE generally cause problems during processing and lead to low and inconsistent mechanical properties of items made from these mixed polymers.

ImerPlast™ technology compatibalises these mixed-polymers, offering stable processing, improved production efficiency, the elimination of phase separation and improvements to important mechanical properties.

Recycled Polymer 25 million tonnes of post-consumer plastic waste is generated in Europe each year.

24.1%, approximately 6 million tonnes, of that enters the recycling system. Sorting it is both time consuming and imprecise, leading to bales of polymer waste of varying quality and type.

Whilst mixed polyolefins have been used for some time in certain injection moulding applications, phase separation, especially in slow cooling applications, has been a barrier for their use in extrusion.

Some waste now has well-resolved recycling streams including those for PET and HDPE bottles.

ImerPlast™ technology brings compatibalisation of the different polymers, helping to maintain impact resistance and increase flexural modulus, even at high mineral loadings.

Problems are particularly evident in recycled HDPE resins with a higher PP content.

Because there is a significant volume of single polymer plastics from bottles entering the waste stream there is a business case to sort the bottles, and because the quality is then high, the polymer can be re-used in the same applications.

ImerPlast™ allows plastic manufacturers to move from expensive, sorted recycled polymers to a more cost effective ImerPlast™ compound.

However, the residual mixed colour and mixed polyolefin waste had very few uses until now.

ImerPlast™ therefore: • Extends the number of useful sources of recycled plastics

Why use ImerPlast™?

The addition of minerals to polymers increases flexural modulus. This tends to diminish toughness.

• Allows a higher recycling rate • Increases the number of outlets for recycled polymer.

Due to the nature of the feed ImerPlast™ is only available in black.

If you are interested in a fully compatibalised, consistent performing recycled polyolefin resin that can improve your profitability and open up new markets for you please contact Imerys.

‘Automatic’ extruder die centering “shatters the rules” for concentricity American Kuhne says it has now completed testing of its new “Automatic Die Centering Technology” using LaserLinc’s laser and ultrasonic measurement system.

The group is using die centering technology originally developed and patented by its partner Graham Engineering for parison sidewall adjustment, for die centering technology for medical tubing applications. The new development includes an AK Fixed Center die head (see image right) where

the die pin center location (relative to the die bushing) is adjusted via touchscreen control of four die pin heaters — as opposed to manual die centering. The heaters are located in the rear mandrel of the die head where they can be heated in an uneven pattern to “flex” the die pin to control its position. American Kuhne has added to the system with the incorpororation of closed-loop control of tubing wall thickness concentricity. The group integrated its control system with an online OD and wall thickness gauge controller.

For the test, LaserLinc incorporated its Triton triple-axis micrometer, UltraGauge+ ultrasonic wall thickness measurement system and Total Vu software with OPC (Object Linking and Embedding for

Process Control). Using OPC, the wall thickness data collected by Total Vu was shared with American Kuhne’s PLC where the closed-loop control is performed.

During the test, the concentricity was intentionally taken out of specification several times and each time the control system recovered to 90% concentricity within a minute, and after five minutes the concentricity was stable at 98%.

According to Tom Shoup, New England Regional Sales Manager at LaserLinc: “I've been around extrusion over 38 years and 90% concentricity seemed to be the acceptable goal for tight tolerance medical tubing. American Kuhne has completely shattered those rules. I honestly would not have believed it had I not been there to see it.”

According to Tyler Ware, American Kuhne Process Engineer: “The LaserLinc system proved to have very robust and fast communications, which allowed our system to quickly and accurately make automatic adjustments to concentricity.”

American Kuhne, Inc. is a supplier of standard and customised single screw extruders, feed screws, and complete extrusion systems for medical tubing, pipe, and profile.

LaserLinc is a manufacturer of noncontact laser and ultrasonic systems for OD, ID, wall thickness, eccentricity, and concentricity across many industries including wire, cable, medical and other tubing, hose, pipe and fibre.

Extrusion blow moulding series launched to market

Extruder group launches latest control system setup

During K 2013, Kautex Maschinenbau launched its new all-electric KBB series of extrusion blow moulding machines.

“Our new generation of machines achieves its high performance levels through less downtime,” said Dietmar Michels, Product Manager at Kautex Maschinenbau. “We significantly accelerated transport movements in the machine as well as the opening and closing movement of the mould, reducing the traversing time for 770 mm from the head to the calibration position to only 0.6 seconds.” The cooling phase has also been shortened. Compared to conventional production systems, the new machine series has reportedly been designed to bring a reduction of 25% in dry cycle times.

“By using lighter materials, we have significantly reduced the moving mass.

In this way, we were able to increase not only the performance, but also to reduce the required drive power,” said Dietmar Michels. There is also a system for recovering energy where the excess braking energy is fed back into the machine or the processor’s network via an intermediate circuit.

A procedure for changing moulds, which is apparently exclusive to Kautex Maschinenbau, allows for further efficiency improvements in the production process. A change of mould can be performed by two operators in less than 15 minutes. An automatic lubrication system provides for an additional reduction of downtime by

At the K 2013 trade show KraussMaffei Berstorff gave visitors the first glimpse at its new central line control system – the C6.

“In our new C6 control system, we have systematically implemented features that have worked well in the past and continue to do so, and we have combined these with state-of-the-art hardware components,” said Peter Roos, President of the Extrusion Technology segment and of the KraussMaffei Berstorff brand. “It fulfills all the requirements in terms of excellent product quality, optimal production setup and transparent production conditions.”

Designed with several monitoring and closed-loop control functions, the C6 control system provides access to the extruders and downstream equipment.

Incorporating with the latest software, the system is also set up for future machine concept requirements, claims the group.

“State-of-the-art multi-touch technology coupled with a high-resolution, 24-inch full-HD screen allow for simple, intuitive operation and an optimal overview,” said Roos. The screen layout has been designed to accommodate a full process overview. Units and functions can be operated and activated via the touchscreen display and non-contact identification using RFID readers has been built in for secure access to the machines.

reducing maintenance. All necessary adjustments for optimising material and the machine settings can be performed during operation. Consequently, the machine does not need to be stopped to adjust the closing or calibration forces.

The four models of the KBB series offer feed strokes from 400 to 1,000 millimeters and closing forces from 10 to 40 tonnes, so that a wide spectrum of production possibilities is covered. As an option, the manufacturer has also developed a new type of remote monitoring via the internet, as well as a virtual training station.

can be customised, and display and parameter texts can be tailored to individual requirements; system components can be switched on and off as required. The C6 control system uses remote diagnostics via the internet and data interfaces to connect to the user’s company network.

A range of different operating variants are available to extrusion shops; these include a console mounted on switching cabinet doors, one which is swivelmounted on switching cabinet, and a mobile version.

MACHINERY ROUNDUP Lab group launches modular 12mm twin-screw extruder

K Show sees blending technology launch New blender technology that aims to improve the cost/performance balance for plastics manufacturers by allowing throughputs to be measured in real time, was unveiled at K 2013.

Launched by suppliers of gravimetric blending and control systems, TSM, this latest product development is said to combine the benefits of its patented reverse auger technology with an ultrafast, responsive throughput measurement.

TSM’s Director of Sales, Declan Byrne, said the new blender has unique advantages and will provide customers with guaranteed quality and repeatability while reducing raw material costs.

“The responsive throughput measurements will benefit plastics producers by giving them real-time control. This will significantly improve the accuracy and consistency of their end product, reduce waste and improve cost efficiency,” he commented. A new control algorithm, which has been developed in conjunction with a UK university, is said to deliver exceptional control allowing performance to be maintained at lower setpoints. The mechanical design is ideal for either new or retrofit installations.

Labtech has launched a new 12mm corotating twin-screw micro-compounder designed to be used with polymers in powder or micro pellets form with an approximate maximum granule diameter of 1.5mm.

It is said to be suitable for the processing of minute polymer quantities for research applications, but can also produce larger quantities having a maximum output of around four kilograms per hour.

The extruder is supplied complete with a stainless steel volumetric hopper feeder with a spiral type screw and a stirring arm (agitator) above the feeding screw. The hopper feeder can also be equipped with twin screws.

Inside the clam shell barrel are segmented screws where each segment can be placed anywhere on the hexagonal screw core shaft for optimum flexibility of screw configurations. The kneading elements are supplied as single sectors that can be placed against each other in various angles, said to enable multiple kneading and shearing functions.

Each barrel zone is equipped with both water cooling and electric cartridge heating which allows for complete process control at each zone of the barrel. Water cooling coupled with the high wattage heating is said to enable fast temperature changes of each zone when changing processing conditions from one compound to another. The water cooling is achieved from fine channels inside each barrel module and regulated with individual solenoid valves from its designated temperature controller.

Labtech says with an L/D extruder ratio of 36:1, the extruder is supplied as standard with an atmospheric venting zone on one of the barrel modules. This can be equipped with a stainless steel vacuum housing, sight glass and manometer, connected to a dedicated extractor pump.

The extruder is designed with a sturdy sub-cabinet containing all electric and electronic components in compartments completely separated from the vacuum pump assembly. The control panel is mounted onto the body of the extruder and contains programmable pressure controller with digital indication of the screw tip pressure, digital RPM indicators for main screws speed and feeder screw speeds and clear warning lamps for any overloads or temperature problems.

SHOWCASE INJECTION MOULDING Engel offers machinery cover packages

IMM customers offered free machine-setting smartphone app

Engel Austria has launched new programmes for the maintenance of injection moulding machines called Engel protect and Engel protect+. The two service packages insure plastics processing firms against repair costs while improving the availability of machinery and systems.

“Calculating maintenance costs is not easy, especially where injection moulding machines are used for a lot of different products and the requirements keep changing,” said Wolf—gang Degwerth, Head of the Customer Service Division at Engel Austria. “With our new service packages, we are enabling customers to plan reliably from the start.”

Where clients sign up to Engel protect, Engel pledges to rectify at no additional cost all damage to production systems supplied by Engel not caused by wear or operation. Spares, transport and technical services are included, regardless of whether these are rendered on site or over the phone.

Engel protect+ includes expendable parts (the only exception to this being

components subject to plasticising wear).

Since the two service packages make quotations and ordering processes superfluous, processors also save time.

Known as Engel plus, the group’s range of maintenance-oriented products and services also include the upgradable ecodriveR energy-saving option, the flomo temperature-controlling water distribution system, oil maintenance, the e-service.24 remote maintenance tool and the e-factory 2 MES solution as well as training and e-learning options.

Wittmann Battenfeld has joined a host of equipment suppliers to offer its customers a smartphone app for online support with their machines. Named ‘WIBA assist’, the app supports users in machine setting. It is based on a materials database which contains the ‘most important’ process parameters.

These can be retrieved directly by users. The values are also used for various calculations. For example, by entering a few parameters, values such as cooling time, cavity pressure, injection pressure, clamping force, dosing volume or screw speed can be calculated.

“WIBA Assist” also provides a function for trouble-shooting, where a description of the most frequent injection moulding faults and defects including suggestions for remedial action can be retrieved.

“WIBA Assist” is available free of charge for iPhones, Android phones and Windows phones.

SHOWCASE INJECTION MOULDING Mould cooling channels can now ‘cross paths’ HASCO’s new technology, named ‘CoolCross Z99/…’ is said to offer ‘new possibilities for the user’ when it comes to designing cooling systems for injection moulds.

HASCO says it is possible to have cooling channels crossing each other on the same plane in a ‘flexible and inexpensive manner’ without any major outlay on

production. The technology has been designed to permit a homogeneous temperature distribution at the core or insert, as well as constant cavity cooling on all four sides for the full duration of the injection moulding cycle. It also prevents hot spots. In addition, protection against rotation (achieved through a locking mechanism) prevents the unintended closure of the cooling channels.

Different independent cooling circuits cross each other on the same plane, making it possible to incorporate small plate thicknesses and inexpensive accessory components in the mould design.

By reducing the plate thickness, use can be made of shorter nozzles, guidance and attachment elements. Not only are the costs of the components brought down, but also the processing costs, claims HASCO. Using the Z99/... permits a reduction in the number of cooling channels, since it is no longer necessary to have a cooling channel in an additional plane. If the

CoolCross is used in thicker plates, the installation depth can be selected on a variable basis. Adapter Z9901/… can then be used to provide support.

New dosing system permits rapid colour changes At K 2013 Sumitomo Demag ran a new peripheral module called activeColourChange. With the product, the group has developed a pigment dosing system which allows extremely short colour change times to be performed when using liquid colours.

The colour is fed directly from a closed system into the metering zone of the melt-filled injection unit. In contrast to colouring with masterbatch, the upstream zones (the feed and compression zones) are kept free of colour, which in theory means that less cleaning is required.

The group demonstrated activeColourChange on its new Systec SP 280 (producing one litre buckets) with three different colours at K 2013. The colour dosing and change system can process with up to five colours. It is integrated into the NC5 plus machine control and is activated and deactivated automatically.

During the colour change process the first liquid colourant is automatically deactivated once the selected product volume is reached. When changing the colour, the screw channel and the front of the screw can be cleaned before the activation of the second colour.

The colour is fed using 'ViscoTainers' - plastic containers with an integrated dosing function, as well as a control and drive unit. To keep equipment clean, all parts of the 10 • WWW.EPPM.COM • NOVEMBER 2013

ViscoTainer that come into contact with the liquid are isolated from the rest of the peripheral components. activeColourChange uses feed pumps which allow reproducible metering of smaller colour doses under high melt counter-pressure. For high homogenisation, the metering zone of the screw is equipped with a mixing section.

RECYCLING

EREMA UNVEILS ‘COUNTER CURRENT’ RECYCLING LINE AT K

On its stand at K 2013 Erema officially unveiled its latest machine for plastics recycling, the ‘Intarema’. The machine is based on patented ‘Counter Current’ technology, which is said to result in increased productivity, flexibility, easy operation and “considerably lower” energy consumption.

Erema says the innovation in the Counter Current system is in the cutter/compactor and tangentially connected extruder, where it circulates material against the normal direction of the extruder, resulting in more material being processed in a shorter time.

Erema says to date, the worldwide technical standard has been a system in which the material in the cutter/compactor moved in the direction of the extruder. The centrifugal forces arising in the process were used for the feeding of the extruder and the treated, warm material was “packed” into the extruder screw. It says the inverse tangential configuration of the Counter Current system now ensures that the extruder screw is filled virtually pressure-free with the preheated material.

Michael Heitzinger, CTO at Erema, described the impact which the new system has on productivity and the quality of the recyclate, saying: “The screw basically takes what it needs, the extruder always has the ideal filling level and is never overfilled, which makes it much better to regulate.”

Results from development trials with existing customers which used inhouse waste from LLDPE blown film production reportedly demonstrate increases in process stability, productivity and flexibility over other systems. “Besides extremely easy operation, a stable and sensitive recycling process is essential to be able to ensure recycling rates of 100% high-quality recyclate in virgin material grade, particularly when processing clean in-house waste from production,” said Heitzinger. The

diagram shows throughput as a function of the processing temperature in the cutter/compactor and illustrates the effects of the improved material intake (see image 1).

In certain systems, the packing and pressure may risk the material ‘sticking’, especially when using very light materials (such as fibres or thin packaging films) or materials with a very low softening point (such as PLA) which could result in less material intake. Erema claims that with Counter Current technology, the improved material intake means that not only is capacity increased, it also stays at a constantly high level over a much broader temperature range.

In post-consumer recycling, where material typically fluctuates in terms of moisture, compactness and other parameters, the new system has been designed, says the group, to ensure that pellets are produced with a high level of consistancy.

Other materials which can be reprocessed with the new system include washed agricultural films, washed post-consumer film flakes (PELD, PE-LLD, PE-HD), films with solid content such as paper, wood or metals and also thick-walled regrind materials from waste automobile and electronic goods, PS cups and PE lids.

Erema gives the example of recycling a car battery to demonstrate the capability of the Intarema system: set up with a single screw extruder (without extruder degassing) and specially selected cutter/compactor tools, polypropylene (PP) from car batteries can be recovered, washed and broken up into chips.

As these are very thick-walled, moist particles (see image), high residence times in the cutter/compactor are required, so the material is dried efficiently and has sufficient time to be warmed thoroughly and homogeneously. The material is then melted in the short extruder screw with “minimum shearing strain”, says the group.

Erema says that the almost pressurefree filling of the screw (which comes from using the counter current) reduces the risk of overfilling, which can cause high shearing and signs of wear. Furthermore, the melting process with minimum shear stress increases the cleaning efficiency of the

melt filter as the size of organic or mineral solid matter is not reduced.

This improves the quality of the recycled pellets, meaning that end products with a considerably higher share of recycled pellets can be produced, including, Erema claims, new battery packs using 100% recycled pellets (see image 2).

Also running on the machine at K, the group displayed its new “Smart Start” control system. One aspect of this setup is an integrated ‘recipe’ management feature, which enables plant operators to save all settings and parameters for specific applications under one ‘recipe name’ and call it up at any time at the push of a button. For simplicity, operators can press the extruder symbol to start the entire downstream process, in sequence.

Similarly, users can push the cutter/compactor symbol, and the cutter/compactor and automatic feeding process will begin.

Intarema also comes with a standby mode which automatically switches the system to standby if there is no input material and reduces it to a lower operation point. As soon as the system is refilled with input material it starts up automatically again.

Also included as standard is Erema’s ‘ecoSAVE’ technology which, the group claims, enables users to benefit from 10% less energy consumption, a reduction in CO2 emissions and lower production costs.

RECYCLING

In Europe, at present, just 6 out of the 25 million tons of plastic waste generated (24%) is recycled. Material recycling facilities collect plastic waste and resell the easily sorted major fractions, such as bottles, to recyclers. The remainder, usually only sorted by density, is mixed polymer and often mixed colour, which until now has had little value and few applications.

This post-consumer, mixed colour, mixed polyolefin waste is widely available but is very difficult and expensive to sort further. When this mixed resin is used in slow cooling extrusion applications such as pipes, phase separation can occur due to incompatibilities between the HDPE, PE and PP. During the recent K Show in Germany, Imerys, a global supplier of minerals and functional additives to the polymer industry, launched ImerPlast, an engineered mineral polyolefin compound designed to

bind a mix of polypropylene and polyethylene together to ensure stable production.

By introducing an active, mineralbased compatibalising agent into the mixed resin, ImerPlast builds networks between the HDPE, PE and PP, resulting in improved extrusion properties and a degree of consistency that is often lacking from recycled HDPE. This inconsistency in behaviour of recycled HDPE occurs because the source of the recycled HDPE changes from batch to batch leading to variations that can on occasions cause customer’s production waste to rise from 5% to 20%.

Mechanically the ImerPlast compound behaves like the mixture of HDPE and PP that it is, with properties somewhere between the expected values of each. By using the mixed waste fraction, ImerPlast can help improve recycling rates. Because less sorting or use of single controlled source resin is required for the

The Bühler Group has launched a new Optical Sorting Station (OSS) system at this year’s K Show.

The system is built on plant engineering, sorting technology, pneumatic conveyors, preconditioners and auxiliary equipment.

The group says that the new system means that processors no longer need to source separate elements from multiple suppliers, and manage multiple relationships.

For flake processing, an optical sorting station features a purifying, refining, sizing and grading stage which can include one or more SORTEX optical sorters. These are linked by all the necessary equipment to convey the product between stages and, if required, to reintroduce it into the system for resorting. Flakes can be fed into one end of the station and collected at the other end – ready for bagging or further processing.

K LAUNCH: THE BÜHLER OPTICAL SORTING STATION

Pallmann, a supplier of size reduction technology unveiled a new grinding system for recycling vulcanized rubber waste back into fine powder for direct reuse in rubber processing during K 2013. Named ‘Karakal’ after a type of wild cat or ‘desert lynx’ it is designed to devulcanize the rubber as it pulverizes it, so that it can be used in place of virgin material.

The unit consists of a twin-roll mill that has been designed specifically for recycling waste produced during the manufacture of technical parts, as well as waste generated when re-treading truck tyres.

It accepts material that has been precut to a particle size of 4mm or less, and which is fed to it continuously by a series of screws positioned along the gap between the rollers. Pallmann has applied for several patents on technology incorporated into the equipment.

“We have already installed the full optical sorting station for several of our plastics customers, including Deceuninck and ITW Poly Recyling.

These companies are beginning to see increased efficiency and yield from their processing lines, which of course leads to higher operating profits.”

in the rubber processing sector, and we wanted to develop a cost-effective process that would enable it to be recycled back into production,” said Mr. Rolf Gren, Senior Executive VP Pallmann Group. “For this, you need to down-size the material into a very fine powder, with particle sizes of under 500 micron and a D50 (median diameter) of around 250 micron — so, really fine powders.”

Large amounts of rubber waste from old tyres are already re-used, but mostly as a low-grade filler in building and construction. Some is also pyrolyzed into carbon black, oils, fuel gas, and other residues.

In the past, cryogenics have been used for producing powder from rubber waste, but this creates particles with cubic geometries, which Gren stated are not best suited for incorporation into new compounds. More recently, conventional roller mills have been used, but these create particles of around 800 to 1000 micron, which is too big for reprocessing operations.

This process is also very energyintensive.

“What you want is smaller particles, with a rough surface,” said Gren.

MATERIALS ROUNDUP FRX Polymers opens full scale halogen–free flame retardant plant FRX Polymers has announced the opening of its Antwerp manufacturing plant dedicated to the production of halogen free polyphosphonate flame retardant (FR) plastics. The first full scale commercial plant will focus on supplying Nofia polyphosphonates, FRX Polymers’ line of homopolymer, copolymer, and oligomer FR materials.

Nofia inherently flame retardant plastics and additives are designed to be more environmentally friendly and less toxic flame retardants, according to the group. Nofia can be used to enhance the flame retardancy with little impact on the inherent characteristics of the targeted polymer or resin. In several engineering resin systems, Nofia retains transparency and enables processability. Nofia polyphosphonates increase the product developer’s toolbox by providing flame retardancy with other desirable characteristics due to its polymer form. For example, Nofia polyphosphonates have demonstrated use in flame retarding biorenewable polymers and recycled fibres and plastics providing a good balance of properties.

The new plant will address the growing demand for Nofia products from multiple markets including electronic devices, lighting and fixtures, fibre for

commercial textiles, automotive, aerospace and building and construction.

“The opening of the new plant strengthens our ability to supply global markets, significantly expands our manufacturing infrastructure and establishes production capabilities to meet increased demand for environmentally friendly alternatives to bromine-based FR products,” said Marc Lebel, FRX Polymers President and CEO. “Being located on Bayer’s open chemical site in Antwerp means most of the basic components that FRX Polymers needs for the creation of its

high-quality flame retardant plastics are produced just a few meters away,” Lebel continued. “It’s vital that our manufacturing facility is in close proximity to our suppliers and in a central location to serve our global customers. This has a positive economic impact and is aligned with the environmentallyresponsible nature of our products.”

SHOWCASE BIODEGRADABLES Analysis: methods for measuring biodegradability

By Paul Clarke, Product Group Manager, Nanoparticle and Molecular Characterisation, Malvern Instruments, and Stephen Carrington, Product Marketing Manager - Rheology, Malvern Instruments With ‘renewables’ a defining feature of today’s polymer industry, Paul Clarke and Stephen Carrington from Malvern Instruments consider the challenges inherent in engineering biopolymers towards market success and examines characterisation strategies that support these efforts. This edited extract examines in particular analysis methods for supporting claims of biodegradability. To read the full article, which takes an in-depth look at biopolymer analysis, visit eppm.com and search ‘Malvern Instruments’.

The displacement of a conventional polymer with a bio-based alternative is a significant technical exercise that relies on being able to engineer a polymer with the properties required both for efficient processing and desirable enduse performance. Understanding biodegradability mechanisms is also essential to substantiate any claims made regarding end of life behaviour, a particularly important focus for products that often enjoy only single use, such as plastic bags. Meeting these requirements requires careful consideration of the best analytical tools for the job.

In this article we take a look at what rheology can offer the biopolymer industry, focusing on how the technique can be applied to support the development of successful products. An experimental study is presented to show how rheology can be used to make labbased assessments of degradation and compostability.

Assessing biodegradability via rheological studies As a result of the increasing standards and regulations relating to polymers, biodegradability has become a crucial parameter that requires accurate quantification. As a result concerted efforts are being made to establish techniques that can accurately measure compostability or degradability, within the lab. Rheological analysis potentially holds the answer with early experimental work suggesting that it can be successfully applied to simulate behaviour in the field.

Rheology tests measure the flow characteristics of a material and, in simple terms, can be applied to investigate whether it exhibits more viscous or more elastic properties or, to put it another way, whether it acts more like a solid or a liquid. A measure of the stiffness of a material is provided by the G modulus which can be further split into two components G’, the elastic modulus, and G’’, the storage modulus.

These can be measured through oscillatory testing with a rotational rheometer, a technique that involves, as the name suggests, applying a sinusoidal stress or strain to a sample

16 • WWW.EPPM.COM • NOVEMBER 2013

and measuring its response. The relative magnitude of the measured moduli defines the viscoeleasticity of the material and indicates whether it is exhibiting more solid- or liquid-like behaviour.

As biopolymers biodegrade they undergo internal changes in structure which can manifest themselves as changes in viscoelastic properties. PLA decomposes through hydrolysis and cleavage of the internal ester linkage. A key feature of rheological tests is that they are very sensitive to such small changes in the internal microstructure of viscoelastic materials, which explains their value for the study of this polymer breakdown. As a sample decomposes it undergoes micro-structural changes that can be measured as a function time via an oscillatory time sweep. The following case study illustrates this approach.

Case study: Using rheological tests to quantify the biodegradability of PLA samples Research was carried out to determine whether rheological analysis could accurately detect polymer breakdown and provide a means of measuring the impact of different variables on degradability. Four random PLA samples (mixtures of both L and D lactic acid) of different molecular weight were exposed to solutions of tap water, water with a lactase enzyme and a slurry of starch in water created to simulate the varying conditions found within landfills. Tests were carried out over a period of 121 days at temperatures of 25 and 50°C. Each day a sample was extracted for oscillatory testing at a single frequency to ascertain the rate at which biodegradation was proceeding.

When all of the data for samples maintained at 50°C are plotted (see figure 1), they sit along a defined curve correlating percentage change in viscosity with time. This is regardless of PLA type, environment or sample thickness. This suggests that the degradation process proceeds via a single mechanism that is independent of the polymer type or environment.

In contrast the data for the samples held at 25°C (see figure 2) suggests that sheet thickness is a determining factor in

Figure 1: Plot of samples exposed to solutions at 50°C6

Figure 2: Plot of samples exposed to solutions at 25°C7

terms of the rate of degradation. When doing this, two distinct curves can be extrapolated both indicating the same correlation between change in viscosity to time. Therefore it is possible to conclude that the overriding dictating variable to degradation at lower temperatures is sheet thickness and that the hydrolytic degradation of PLA is diffusion controlled.

The significance of this experiment is that it shows how land fill environments can be simulated in a laboratory and how the rate of degradation can be clearly measured as a function of the change in viscoelasticity. With regulatory bodies becoming increasingly litigious in regards to the materials industry, charting biodegradability is not only key

to development but a growing legal necessity.

A sustainable future It seems clear that in the future the polymers industry will be increasingly shaped by ethical, economic and legal issues and the sustainability agenda. A growing biopolymer industry holds out the promise of advantageous solutions that address many of the issues faced.

New analytical strategies are required to ensure delivery on this promise.

Rheology testing has been shown to provide useful information both during development and when assessing the degradability of biopolymers and therefore has a valuable role to play in advancing biopolymer application.

MATERIALS

SHOWCASE BIODEGRADABLES New range launched to boost biodegradability Chemicals group Perstorp launched a new line at K named ‘Capa’, designed for biodegradeability enhancement. The group says that considerable investments have been made in caprolactones (a biodegradable polyester) to to deal with issues surrounding sustainability, biodegradability and product safety.

Perstorp says that its caprolactones enhance the properties of bioplastics allowing them to be used for “new market opportunities and applications”.

Speaking with EPPM at the show, Linda Nilsson, Project Manager stated that the product is tested to the European standard EN13432. She said that the tests were conducted in such a way that was comparable to household composting, rather than under industrial composting conditions. Under optimal conditions, she said that Capa can biodegrade in 40 days. Nilsson confirmed that the tests took place at an independent test institute in Sweden.

According to the group, the Capa line was designed to improve several mechanical properties as well as accelerating the biodegradation of biopolymers. Perstorp’s main claim for the product is that: “Bioplastics with Capa biodegrade quickly in the right conditions — you can use domestic composting,

rather than industrial requiring a higher temperature.” It is also said to offer excellent tear properties by adding mechanical strength, and making the bioplastic more flexible, so that it elongates and stretches rather than tearing. The low temperature performance also allows for bioplastics to be used in cold environments.

The low melting point reduces energy consumption when processing. By adding Capa, Perstorp claims that PLA can be used in film applications. It can be blended with PLA and starch-based polymers. It can be used in disposables – for plastic bags, compost bags, coated paper and one-time plastic cutlery, and in renewables – for cutlery, trays and items that need to last a year or two. Bioplastics are now broadening out into electronic equipment, such as mobile handsets and casings, and making inroads into automotive parts too. Perstorp said that “Capa is an essential part of this journey into these new market segments”.

Perstorp also showed new products for intumescent flame-retardants, nonphthalate plasticizers and heat resistant transparent thermoplastic co-polyesters.

Biodegradable packaging - the best thing since sliced bread

The Technological Institute of Plastics (AIMPLAS) exhibited at K, discussing its claims that it is making developments in biodegradable packaging ‘made from left over sliced bread’, amongst others.

On display was what AIMPLAS claims is “the first biodegradable packaging for the cosmetic industry”, as well as packaging for the chemistry and healthcare sectors.

AIMPLAS says it is also making strides in the field of biodegradable packaging for the food industry. On display was a packaging application for fruit and vegetables which, in addition to being biodegradable, is also active, increasing the food lifespan by more than 15%.

Even more specifically, AIMPLAS is also developing a new type of packaging for semi-preserved fish (anchovies). This new product will have a sandwich structure, using co-injection technology.

The outer layers will be made from polypropylene, whilst the inner layers will be made from wheat starch, which

acts as an oxygen barrier. AIMPLAS is saying that the packaging will be recyclable, because the separation of polypropylene and starch is simple, the starch completely dissolves in water.

Finally, the group discussed its work in using by-products from the agri-food industry. In this context, AIMPLAS claims that new packaging is being developed for the baking industry, which is reportedly 100% biodegradable and made from left over sliced bread, as well as a biodegradable juice bottle made from waste water.

AIMPLAS announced the date of the Fifth International Seminar on Biopolymers and Sustainable Composites, one of the main meetings in the sector on a worldwide scale. The event is to be held from 6th to 7th March 2014 in Valencia.

APPLICATION FOCUS Automotives

Solvay EP brings future applications to K masses Solvay Engineering Plastics introduced new products for the automotive market during K 2013, with plenty of sample applications on hand to demonstrate their effectiveness. First up was a road-saltresistant Technyl eXten grade which broadens the group’s portfolio for demanding automotive thermal management systems, targetted for vehicles in regions with extreme weather conditions.

Initially developed for Japanese and Korean carmakers, this new material demonstrates high chemical resistance to calcium chloride, the preferred road salt used in countries with lower freezing temperatures, such as Russia.

Valeo, a global player in the automotive industry, reportedly selected Technyl eXten because of its cost/performance ratio compared to metals or alternative plastics. The material obtained full approval after rigorous testing and will be used for radiator-end tanks in a future Renault-Nissan platform.

“With the continuing need to reduce engine emissions and fuel consumption, the objective in engine thermal management is focused on maintaining all engine components at their ideal operating temperatures from warm-up until full stop,” said Dr. G. de Pelsemaeker, R&D and Program Director for Valeo’s Thermal Systems Business Group. “In response, we are developing cooling systems able to manage the heat dissipation of increasingly complex engine components, while resisting to extreme driving conditions. Solvay Engineering Plastics supports us with a

full range of Technyl materials and solutions improving the time to market of lightweight, energy efficient and increasingly compact, modular designs.”

Solvay Engineering Plastics offers a range of hydrolysis-resistant Technyl ‘34NG’ products ranging from 25 to 50% glass-reinforcement. They are specifically designed for every part in contact with glycol, such as radiator-end tanks, expansion tanks, thermostat housings and oil modules. In addition to assisting Tier one suppliers in the material selection and validation, Solvay Engineering Plastics also provides OEMapproved testing capabilities to validate parts.

“Building on the success of our historical position in providing pioneering materials for automotive cooling systems developed with major industry players, we are fully committed to pursuing our investment in product innovation to enable our customers create new solutions for thermal management applications,” said Peter Browning, Global Automotive Market Director for Solvay Engineering Plastics.

Also being discussed at the Solvay stand was a collaboration with TrelleborgVibracoustic, a specialist in automotive vibration control. The two firms have developed a faster way to design and develop thermoplastic engine mounts.

“When designing high performance engine mounts it is essential to provide our customers with products which offer greater endurance coupled with less weight, therefore we are constantly

Applications on the rise for PEEK use in cars Victrex, a manufacturer of highperformance polymers says that its PEEK has been shown to offer “a reliable and efficient replacement for metal gears, leading to overall reduced fuel consumption and improved responsiveness.” The group states that the demand for PEEK and similar plastics in the auto sector continues to rise.

Victrex PEEK 450G and its newlyintroduced variants reportedly offer: an enhanced lifetime for parts in lubricated applications; no swelling or loss of strength due to moisture absorption; less noise and vibration; low friction and wear; enhanced corrosion resistance; and a reduced need for lubrication, including the most demanding requirements within the engine or actuators.

In the automotive arena, Victrex has teamed up with customers, including US company Melling Engine Parts, which used Victrex WG polymer for a small 18 • WWW.EPPM.COM • NOVEMBER 2013

bushing in a water pump. Since this polymer can withstand high loads at elevated temperatures, while reducing frictional losses, energy consumption and component wear and tear, pump lifetime was extended and warranty requirements met.

Likewise, Victrex WG101 grade polymer is being used to minimise frictional losses within similarly extreme environments and it provides outstanding compressive creep resistance. In addition, this grade, and Victrex PEEK polymers generally, can withstand the aggressive automotive fluids and the high temperatures of today's transmissions, with no detectable thermal degradation at 250°C for more than 5,000 hours.

The result, according to customers, is optimised efficiency, reliability and durability, and increased product lifetime.

looking for lighter materials, replacing metals with plastics,” - said Ludovic Chauvet, Engineering Expert at TrelleborgVibracoustic.

“Our choice of utilizing MMI Technyl Design was determined by the quality of the material anisotropic data available for Technyl products. Building on the results, we developed a unique solution for designing and predicting the performance and manufacturing of structural components, while taking into account the production process,” he added. “Together with our FIAPLAST programme for mechanical dimensioning, this unique approach enabled us to decrease the mass of our customers’ engine mounts by 30 percent and reduce time to market.”

MMI Technyl Design is a service that Solvay Engineering Plastics “offers customers to meet the light-weight challenge.” It is supported by a comprehensive materials database and allows for a wide range of calculations when integrated with injection process modeling. The group describes it as “a powerful and high-performance solution allowing [the user] to accurately predict the performance of injection moulded parts made from Technyl materials and thereby significantly reduce the mass and cost of the applications, for which crash and fatigue resistance are key requirements.”

The first applications developed by TrelleborgVibracoustic for engine mounts with significantly reduced mass were at Peugeot-Citroën for its 3-cylinder engines.

Today, applications can also be found at Renault-Nissan on some Renault, Nissan and Dacia models. By 2016, TrelleborgVibracoustic will reportedly be producing several million thermoplastic engine mount components annually.

“For the past several years, our specialist teams and our advanced services such as MMI Technyl Design have been pushing the boundaries of metal replacement in the engine compartment,” said Peter Browning, “We are proud of our partnerships with automotive manufacturers and their suppliers being able to help them create value at each production phase from design through to industrialisation.”

APPLICATION FOCUS Engel not hitting the brakes on composites R&D Engel used K 2013 to highlight, among other things, its developments in composite technologies, demonstrating the production of brake pedals and latch covers for the automotive sector.

“Lightweight construction and injection moulding are inseparable key concepts for meeting the increasing demands of the transport and mobility sectors,” said Peter Egger, Head of Engel Austria’s technology centre for lightweight composites. “Aircraft construction has been given the direction, but the well established processes used in that industry to make lightweight components cannot be transferred to car manufacture, which is dominated by high unit quantities.” The composite technology centre, which was opened in 2012 at the group’s large-scale machine factory in St. Valentin, Austria, was designed to develop new processes – often in connection with new material systems – for the car industry. “It is only interdisciplinary competence that makes fibre composite projects successful,” said Egger. “Composite technologies need ‘composite’ development; this means development has to occur in an alliance with others.”

Engel updated visitors on the progress of the research, stating that currently, the technology centre is focusing on the processing of semi-finished thermoplastic products (thermoplastic composite fabrics and tapes) and on reactive technologies that use thermosetting and thermoplastic systems, such as HP-RTM and in-situ polymerisation. Peter Egger said: “At this point, it's impossible to say which technology will be the preferred choice for specific applications on a regular basis in the future, but overall we believe that all four of these technologies have great potential.”

At K, the group demonstrated the production of a ‘geometrically optimised’ stress-resistant composite brake pedal manufactured using a one-shot process.

The Engel ‘organomelt’ method used involves composite fabrics (semi-finished thermoplastic products reinforced with continuous fibres) being heated in an infrared oven, preformed in the mould of an injection moulding machine and immediately overmoulded with polyamide.

This set-up produces ready-to-install parts that don't require any extra cutting, whereas traditional metal brake pedals can’t be made in a one-step process. By replacing metal, the component weight is also reduced by about 30% without impairing the load-bearing capacity.

The system used a vertical Engel insert 200 single injection moulding machine with the group’s ‘easix’ multi-axis robot and an infrared oven with a shuttle system. Egger said: “As well horizontal as vertical injection moulding machines can be used for ENGEL’s organomelt technology. We customise every system solution so that it is adapted perfectly to the application, the manufacturing environment and the degree of flexibility desired by the respective customer. The solution’s overall efficiency is always the most important thing.”

The infrared oven, which has been developed by Engel itself, allows a sensitive, time-optimised heating process for composite fabrics, including thick-walled types. Both the oven and the multi-axis robot are fully integrated into the control unit of the injection moulding machine meaning that all the components access the same database.

Another application demonstrated Engel’s developments in high-pressure resin transfer moulding. The system produced latch covers for KTM’s X-Bow

sports car on a v-duo injection moulding machine.

The v-duo is a large-scale vertical machine, which made its trade show debut at K this year. It was developed specifically for fibre composite applications, but could also be used for processes requiring high cavity pressures.

“Compared to conventional presses, the Engel v-duo is about 60% lighter in weight and has only 50% in terms of height,” said Bernhard Lettner, Product Manager for the Engel duo series. He added: “This reduces the efforts and costs involved in laying a base for the machine. In many cases, existing

building structures can be used.” The clamping unit can be accessed from all four sides instead of just two, which speeds up maintenance work and also simplifies automation. In addition, handling devices can be integrated to move straight into the mould area. By using sliding tables, insertion tasks can be carried out outside the clamping unit, which reduces the cycle time even further for many applications.

The standard version of the Engel v-duo also comes with the ecodrive servohydraulic system.

2013: SHOW REVIEW 16-23 October 2013, Düsseldorf, Germany On-site sales at K ‘worth millions’ says Messe Düsseldorf Messe Düsseldorf, organiser of the K 2013 trade show issued a statement on the final day of the show saying that expectations for business at the show were exceeded. It says that exhibitors have reported numerous concrete project enquiries, negotiations with visitors and a large number of business deals, some of which were concluded on-site and were worth millions.

Chairman of the Exhibitors’ Advisory Board for K 2013 Ulrich Reifenhauser said: “We had not expected visitors’ willingness to invest to be this high. The many innovative products and applications premiered in Düsseldorf met with great interest from trade visitors. And the innovations were not just admired as many, very concrete negotiations were held and contracts were signed. Many customers are

extending their capacities and are investing in new technologies to sharpen their global competitive edge.

We very confidently anticipate strong post-fair business and expect continuing growth in our sector.”

The group has reported that approximately 218,000 visitors came from over 120 countries. Werner Matthias Dornscheidt, President & CEO of Messe Düsseldorf said: “Once again it becomes very clear that K is and remains the most important event in the rubber and plastics industry. This is where new technologies are premiered alongside fully matured further developments and this is also where orders are placed for these innovations.

Foreign visitors to K 2013, in particular, showed an extremely high willingness to invest and one in two visitors came to

Düsseldorf with specific purchasing intentions in mind.

Even if the size of delegations from the individual purchasing companies dropped slightly, no firm producing or using plastic goods missed this chance to find out about the innovations of today and the trends of the future at K 2013.”

The show was characterised by a string of major announcements and revelations - including many that were almost entirely unforeseen. Whether or not this acted as a trigger for the impulsive upswing in on-site business

remains to be seen as more statistics emerge in coming months. For now, EPPM has selected just a few highlights from the event. The next show will be held from 19th-26th October 2016 - see you there!

breaks the mould with additive manufacturing launch On the evening before the official opening of K 2013, Arburg unveiled to the plastics press its new ‘Freeformer’ machine based on additive manufacturing technology, and to accompany it, the patented Arburg Plastic Freeforming (AKF) process. The idea behind plastic ‘freeforming’ is that no moulds or cavities are required to produce complete parts.

In the AKF process, 3D CAD files are processed directly by the Freeformer, standard plastic granulate is melted and ‘droplets’ of plastic are released from the liquid melt. By dispensing the droplets, the component is built up layer-by-layer (as in additive manufacturing).

The group said that it integrated certain concepts from its experience in injection moulding technology. The key feature of the Freeformer, which became the topic of many discussions throughout the show, is that it is capable of processing

20 • WWW.EPPM.COM • NOVEMBER 2013

with conventional plastic granulate, rather than prefabricated materials such as powders or strands, which tend to make the material, the processing and therefore the parts more expensive. It also features low material consumption which is important, as it operates without support structures and therefore produces no waste. This saves on resources and allows cost-effective production.

Arburg said itself that the Freeformer, which was ‘launched’ at regular intervals on each day, accompanied by a ‘freeform’ dancing display, did not attempt to ‘reinvent the wheel’. It uses conventional material processing principles, operating in essentially in the same way as an injection moulding machine.

The unit is filled with standard plastic granulate, and a heated plasticising cylinder which creates the melt in the discharge unit. Its patented nozzle closure with high-frequency piezo technology enables fast opening and closing movements to produce the plastic droplets under pressure, from which the plastic part is built up “droplet-by-droplet”.

In the Freeformer, the discharge unit holds its nozzle in a fixed vertical position — and the component carrier moves

instead. In addition to a standard component carrier that can move along three axes, a version with five axes is available, for implementing undercuts without the need for a support structure.

Due to the flexibility of the design, two materials or colours can be processed with one Freeformer equipped with two discharge units. As a result, flexible parts with both hard and soft textures can be produced, as well as parts with a special appearance or texture.

The ethos surrounding the design is the idea of making complex technology simpler to use. The parameters required for parts are built using the Freeformer control system. This processes 3D CAD data from STL files automatically through slicing, and the production begins.

The ‘gesture-controlled’ mult-touch

screen makes things simpler, with Arburg describing the whole process as “loads of fun”. Herbert Kraibuehler, Managing Director, Technology and Engineering said: “On the one hand, we offer production equipment for large unit volumes in top component quality using the injection moulding process with our extensive ALLROUNDER range.

“On the other, we are offering a new machine and a new process for additive manufacturing, enabling small unit volumes to also be produced in high quality and opening up new opportunities in terms of design freedom. This is what the freeformer and ARBURG Plastic Freeforming are all about.”

K 2013: SHOW REVIEW Compounder installation line for bio-compounds announced

Visited Then before you buy, why not check out During the K Show, B&P Process Equipment made the announcement that RheTech, Inc., a major thermoplastics compounder supplying the transportation, construction, electronics and consumer markets, has chosen the group’s TriVolution compounding system to process its RheVision range of bio-fibre reinforced polypropylene compounds.

RheVision compounds use true bio waste products that replace traditional compound minerals (such as talc) that have a larger energy footprint and have a finite supply in the future. RheVision compounds reduce the total carbon footprint and have lower energy requirements to manufacture when compared to fillers such as fibreglass and talc. “Rhetech selected the new B&P TriVolution compounding system because it offers the right combination of attributes we need to achieve the quality and performance for our bio-fibre applications� said Jim Hicks, Senior Director of Process Engineering, RheTech. “Some of those attributes include a better combination of mechanical shear and heat for compounding RheVision products, and more distributive and dispersive

compounding than conventional twinscrew systems. In addition, the TriVolution system can do this in half the footprint of a conventional twin-screw system.�

Michael Lazorchak, Product Manager, B&P Process Equipment, added: “TriVolution has been designed to meet the demanding processing requirements of RheVision’s bio-fibre reinforced compounds. B&P and RheTech, a longtime customer of ours, worked collaboratively on the design and build of this system.�

The TriVolution compounding system, which is expected to be ready by summer 2014 and installed at RheTech’s Whitmore Lake, Michigan facility, is said to offer high throughput at slower screw speeds, meaning less wear and tear, less consumption of replacement parts and less downtime. It can also reduce specific mechanical energy (SME) by as much as 60%, which means the use of less motor energy. In fact, the group states that as a whole it has less overall energy consumption than a comparable twinscrew extruder by as much as 80%.

Finally, the system reportedly offers improved temperature control with an elongation flow that is better for achieving dispersion without excessive heat.

K 2013: SHOW REVIEW Conceptual vacuum loader to offer system flexibility At K, Kongskilde, a specialist in material and process waste handling equipment discussed its new concept, the CVL, which is targeted at the conveying of components produced in batches or as a batch loading system for production processes. Pneumatic conveying systems with the CVL unit can be designed as a complete vacuum system conveying the components from a pickup point to the discharge point without any moving parts in contact with the components. The flexibility of conveying parts pneumatically is apparent, says Kongskilde, when compared with mechanical conveying, as floor space requirements are significantly lower, so

flexible installation and changes to production layouts are possible. The parts collected in the CVL unit are discharged gently in batches with a customised sequence and no pressure flow.

Designed for gentle conveying and separation of parts in a flexible pneumatic system, Kongskilde has designed two conceptual CVL separators with a geometry and function that allows the parts to be decreased at speed and collected without being in contact with any rotating machine parts, and with a minimal risk of direct impact between the material and fixed machine apparatus.

The CVL Loaders have a built in holding chamber where the components are collected before they can be discharged in batches. The loaders have built-in pneumatic cylinders, one closing the flow of air and a second one opening the material outlet which operates in sequence. The holding capacities in the two sizes of CVL units is one of the factors (together with the air velocity in the system) which determines the capacity of the units.

Floor space is valuable in a production area and installing a de-central or central pneumatic solutions frees up floor space. The Kongskilde CVL concept is a flexible alternative to traditional

horizontal and/or incline mechanical conveyors.

Kongskilde UK Ltd says it offers customised system solutions, where customer needs and specific requirements are taken into consideration, before the group begins design and collates a proposal.

The new Kongskilde Component Vacuum Loader concept series will reportedly enable its design engineers to put together “new and unique highlyefficient systems with sequence suction for the benefit of any present or new Kongskilde customer.”

K on Film: Extruder group draws crowds with live demos Hosokawa Alpine, a brand associated with film extrusion equipment, reported a successful show, with a host of technologies running live every day.

In-line with what it calls a ‘shift’ in the trend from 3-layer to 5-layer films, the group presented a versatile 5-layer blown film line with output rates of up to 1,000 kg/h. The HXS extruders were driven by water-cooled asynchronous servo motors. The line is controlled via the ExVis 2.0 software with a one-touch system. Both the patented FBF 16-40 X die head, which was equipped with a 400 mm die and the cooling system were designed for high throughput rates.

Across five days of the show, the film was also oriented inline by an Alpine MDO 20/11 inline film orientation line with an operating width of 2,000 mm, 11 rolls and an outlet line speed of ≤ 200 m/min. On those days visitors were able to view the newly developed and patented ‘TRIO TRIO’ system in operation — a profile control system that reduces process-related waste web scrap by up to 50%. At the end of the demonstration, the waste web scrap was compounded by a repelletizing extruder. During the demonstrations, the lines processed resins from Borealis, ExxonMobil, SABIC and Total.

Another display was the Alpine Turret Winder ATW 20 with 2,000 m working width in a space-saving stack-setup. The winder works at controlled low winding pressures and allows winding in clockwise and counterclockwise mode as well as glueless winding.

Finally, the group showed its ‘X’ die head for 11-layer production. For processors operating with 11-layer technology, this die head offers a combination of different functional layers and reduces production costs, claims the group. Further savings are made possible by replacing laminated structures with extruded composites.

There is a particularly wide range of potential applications for 11-layer film in the food packaging segment.

KraussMaffei Group announces ‘acceleration’ of subsidiary restructuring At the recent K Show in Düsseldorf, The KraussMaffei Group revealed that it is now “accelerating the reorientation” of its subsidiaries in Europe, Asia and Latin America.

The group emphasised that all brands will still be acting independently worldwide. “We are still going to pool our strengths and competencies on local markets in a practical way, and also to combine our forces. In particular, customers welcome the fact that they can choose the right product for them and the right service of the right brand 24 • WWW.EPPM.COM • NOVEMBER 2013

from an extensive service portfolio according to their individual requirements,” said Jan Siebert, Chairman of the Board of Management (CEO) of the KraussMaffei Group. The “accelerated reorientation” involves the opening up of all three brands (KM, KM Berstorff and Netstal) to the Mexican market, effective January 1, 2014. The group’s own Mexican subsidiary will sell all products from all three brands. The contract between Netstal and the agency Eurotexa has been terminated.

Also effective from the beginning of 2014, the two subsidiaries of KraussMaffei and Netstal in France will be merged under one roof.

In the first quarter of 2014 in Benelux, the subsidiary of Netstal in Belgium and the subsidiary of KraussMaffei in the Netherlands will be merged. In the Asia-Pacific region the subsidiary of KraussMaffei and KraussMaffei Berstorff in Thailand will take over responsibility for the sale of Netstal products effective during the first quarter of 2014. Netstal's subsidiary in

Singapore will be retained as a sales and service center. “We have started the implementation measures, and will inform our customers in the regions and countries in good time about the local completion and the names of the contact persons. Customers can contact the existing units up until then. This process ensures that all brands will still be independently represented on the market,” added Siebert.
