Zero Halogen Flame Retardant Thermoplastic Polyurethanes (ZHF TPUs) for Wire & Cable Applications
Thermoplastic polyurethanes (TPU) are a class of polyurethane plastics with many exceptional properties including elasticity, high tear strength and resistance to oil, grease and abrasion. Technically, they are elastomers of linear segmented block copolymers composed of hard and soft segments. TPUs were first developed by The Lubrizol Corporation (then The BFGoodrich Corporation) in the 1950s. ESTANE® TPUs were patented and introduced commercially in 1959. Unlike many commodity elastomers like polyethylene (PE), polypropylene (PP), nylon 6 and polyvinyl chloride (PVC), the TPU chemistry allows the creation of a wide range of products with hardness ranging from about 65 Shore A to 85 Shore D.
