Estane Engineered Polymers, a business group within The Lubrizol Corporation, has developed Estane X-1311 thermoplastic polyurethane (TPU), a material that delivers a Limited Oxygen Index (LOI) of 40, developed for cable jacketing and molding. The industry is placing greater emphasis on the development of new compounds that have higher LOI to reduce flame spread while maintaining good flexibility and abrasion resistance. X-1311 TPU meets this industry demand for wire and cable jacketing used in applications such as robotics, industrial equipment and mass transit systems where high LOI and long term, flexible materials are necessary.
“The material combines great flame properties, abrasion resistance and low heat release while maintaining good mechanical properties for extrusion and injection molding,” says Chris Boyher, industrial marketing manager for Estane Engineered Polymers. “X-1311 TPU provides a shore hardness of 53D with an LOI of 40, extending our current offering by 20%. Our new product achieves a UL-94 rating of V-0 on the vertical burn of a 75 mil sample thickness.”
