Osnabrück, Germany - Huntsman has developed a new polyether-based polyurethane with low melt properties that it says is easy to process and is suitable for coating textiles by calendaring.
Huntsman said Irogran A85 P 5050 DP thermoplastic polyurethane (TPU) was developed to increase the range of products available to specifiers in the textile lamination industry. It can be applied using calendaring, a technique used to give fabric a smooth, glossy, hard-wearing finish.
The product can be used to produce durable coated fabrics for inflatable boats, rafts, life preservers and safety jackets; general-purpose tarpaulin sheets; and membranes for flexi-tanks and conveyor belts.
"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," said Helmut Witt, account & business development manager at Huntsman Polyurethanes, in a 16 Oct news release.
Irogran A85 P 5050 DP has strong rheological and morphological properties, which can have a positive impact on production efficiencies, helping to stabilise processing, deliver a high output rate and reduce energy consumption, "ultimately enabling manufacturers to save time and money," Huntsman said. It also has good hydrolysis performance plus chemical and microbial resistance, the company added.
