Reusable
Polyphenylsulfone Ultrason P 3010 offers durability, high-temperature resistance and design versatility for multiple cycle usage
to-go mugs for a sustainable lifestyle
Medium-viscosity injection-moulding and extrusion grade BOTTLE manufacturer Yiwu Midi Technology, Zhejiang, has selected Ultrason P 3010 from BASF to produce reusable to-go mugs for the market launch of its new business segment. Because of its durability, hightemperature resistance and design versatility the BASF polyphenylsulfone (PPSU) offers a unique combination of lifestyle attributes and sustainability for high-quality to-go cups that are lightweight, shatter-proof and fashionable:
At the same time, the BASF thermoplastic polymer contributes to less packaging waste as the mugs can be reused many times and thus support a circular economy: Ultrason P 3010 is a medium-viscosity injection-moulding and extrusion grade with temperatureindependent properties spanning a wide temperature range from -30 to +180°C. It is also food contact compliant in the US, the EU and China. “ The slightly honey-coloured tint of
Ultrason and its good processability make the mugs to stand apart from those available in the market today. The mugs by Yiwu Midi Technology have two air vents, an additional straw opening and a hand grip ring made of silicone, making them practical in use and elegant in appearance at the same time. Ultrason P 3010 can be easily manufactured in combination with other materials like silicone. www.ultrason.basf.com

Reducing the carbon footprint of footwear production COVESTRO, textile technology company Huafeng and green fibre technology company Cyclone from China have jointly developed a solution to produce high-quality running and sports shoes in a much more sustainable way than before: recycled fabric made from Cyclone recycled polyester (rPET) yarns is used as the shoe upper and selectively coated
using Huafeng’s HAPTIC technology. In the process, Huafeng uses a polyurethane dispersion from Covestro’s INSQIN portfolio, half of whose carbon content comes from bio-based raw materials. The greenhouse gas emissions for each pair of shoes produced in this way are around 230 grams of CO2 equivalent less than a pair using
conventional fossil-based PU dispersions and virgin PET fabric. Impranil eco DLS, as a partially biobased binder, is part of the INSQIN range of waterborne textile coating resins. Its use contributes to reduced greenhouse gas emissions with around 60 grams of CO2 equivalents per pair of shoes. The value comes from internal calculations verified by independent external experts. It is obvious that the difference in the CO2 footprint becomes even greater when solvent-based PU textile coatings are used for comparison. The use of fabric based on recycled PET yarns mitigates greenhouse gas emissions by about 170 grams of CO2 equivalent per pair of shoes. Covestro, Huafeng and Cyclone have developed a material solution to produce high-quality running and athletic shoes much more sustainably than before
