CLEVELAND, OH & OEVEL, BELGIUM -- The Lubrizol Corporation , is further expanding its already broad Non-Halogen Flame Retardant (NHFR) portfolio with the introduction of a new grade called Estane® ZHF95AT3 TPU. This grade was formulated to respond to an industry need for NHFR thermoplastic polyurethanes with improved flame resistance properties.

Flame retardant TPU compounds have been used for nearly 30 years as wire and cable jacketing because of their durability and flexibility. Estane® ZHF95AT3 TPU extends the range of flame retardant properties significantly. This grade is UL-listed V0 and has a high LOI (Limited Oxygen Index), above 35, compared to a normal level of 25 for the NHFR thermoplastic polyurethanes currently found in the market. "Estane® ZHF93AT3 TPU will allow cable manufacturers to meet more stringent flame retardant specifications such as cable tray test IEC 60332-3," says Gert-Jan Nijhuis, marketing manager extrusion EMEAI for Estane® Engineered Polymers.
