Huntsman introduces new TPU product

19/10/2010
Huntsman Polyurethanes has developed a complete plasticizer-free thermoplastic polyurethane (TPU) for the footwear industry that has a Shore hardness of 65A. The product, Avalon 65AS, was unveiled to the sector at international trade fair SIMAC (Bologna,12–14 October 2010).

Adding to Huntsman’s range of soft, durable, injection mouldable materials, Avalon 65AS offers good anti-slip resistance and is good for bonding to midsole PU-systems, the company said, adding that it is “a cost-effective solution that can be processed on standard injection moulding equipment and roundtable carousels”. Currently undergoing customer trials, the new product will become widely available during 2011.

Alfons Tremml, commercial manager for footwear at Huntsman, said: “Historically, the production of TPUs with a typical hardness of 65 Shore A has required the use of a plasticizer. However, by carefully selecting ingredients and making adjustments to the catalysts we use, we have eliminated the use of this additive and created a brand new plasticizer-free product. Discussions with our customers led us to take the first steps in researching and developing Avalon 65AS. Listening carefully to their ideas and understanding their requirements has enabled us to develop a TPU grade that helps them conform to new manufacturing legislation and green standards.”
