The new thermoplastic polyurethane (TPU) Irogran A 85 P 4394 HR TPU for high performance fabrics for outdoor clothing and other consumer and industrial applications is a highly versatile elastomer, which can be easily extruded and added to polyamide and polyester materials to give them a protective, durable, waterproof layer.

The TPU by Huntsman Corp., The Woodlands, TX/USA, was developed for use in the manufacture of performance garments that need to shield wearers against the elements while they experience outdoor adventures. Added to fabrics, as an extruded film, the TPU can give items of clothing, e.g. raincoats, a highly durable finish, combined with a soft touch.
With a high tensile strength, extruded films made from this TPU can aid the stretch and recovery of the materials. This special grade also offers good levels of abrasion and tear resistance. With a high melt strength, it is very stable during production. Tolerant to high forces in its melted, blown state, extruded films made from this TPU are far less likely to break during processing.

Depending on the end-application, films made from Irogran A 85 P 4394 HR TPU can be engineered to have different surface finishes, including gloss, smooth and matte effects.
