Polyether-based low-melt polyurethane targets textile coating by calendaring

Huntsman Advanced Materials (Duxford) : 19 October, 2012  (New Product)
Huntsman has developed a polyether-based polyurethane with low melt properties that is easy to process and is suitable for coating textiles by calendaring - a technique used to give fabric a smooth, glossy, hard-wearing finish.
Polyether-based low-melt polyurethane targets textile coating by calendaring

Irogran A85 P 5050 DP thermoplastic polyurethane (TPU) has been developed to increase the range of products available to specifiers in the textile lamination industry. The product can be used to produce durable coated fabrics for inflatable boats, rafts, life preservers and safety jackets, as well as general-purpose tarpaulin sheets and membranes for flexi-tanks and conveyor belts.

Created from a special formula and via a proprietary production process, the new material combines abrasion resistance and tensile strength with a wide processing window. Irogran A85 P 5050 DP offers excellent rheological and morphological properties, features which can have a positive impact on production efficiencies, helping to stabilise processing, deliver a high output rate and reduce energy consumption. Additional product qualities include good hydrolysis performance plus chemical and microbial resistance.

Helmut Witt, Account and Business Development Manager at Huntsman Polyurethanes, said: “We recognised some time ago that it would be beneficial to develop a TPU that could surpass existing polyether materials and be used by manufacturers in the technical textile industry that routinely need to coat fabrics for a variety of applications.”
