Dusseldorf, Germany – Huntsman has unveiled its new thermoplastic polyurethanes for the wire and cable industry at Wire, the international trade fair in Dusseldorf, Germany.Huntsman said that the new products, are designated Irogan and broaden its range of polyether-based TPUs for the market; The new grades include UV-stabilised TPUs for offshore applications and high flame-retardant grades.
Two new high performance ether grades are Irogran A 80 P 5039 and Irogran A 95 P 5044, said Huntsman. The A 80 P 5039 grade is designed to be softer than existing grades for highly flexible cables. The A 95 P 5044 grade is harder solution and gives cable makers the chance to reduce wall thickness and save money, Huntsman says. The firm adds that both materials are designed for cable jacketing for sensor cables
Huntsman said that in offshore applications, cable solutions need to offer high UV stability. IrogranA 85 P 4394UV and Irogran A 92 P 4637UV are new UV resistant grades for the off-shore market and are used where cables will face extreme environmental conditions, said the firm.
Irogran A 89 P 5028DP and Irogran A 89 P 5012DP, were developed to offer offer hydrolysis and microbial resistance, and close the gap between the existing Shore A 85 and Shore A 95 products available in the Huntsman portfolio, the firm said.
Huntsman said that the new materials offer high flame retardancy without compromising physical or functional properties. Irogran A 89 P 5028DP is a harder version of Irogran A 85 P 4380, said Huntsman. The new grade gives good extrusion and dimension stability, meets UL 94 V0 standards and is suited for technical extrusion and injection molding applications.
