NOVELTY - A thermoplastic polyurethane elastomer comprises 60-80 pts. wt. thermoplastic polyurethane, 30-45 pts. wt. p-phenylene diisocyanate, 40-55 pts. wt. epoxy resin, 5-9 pts. wt. graphene oxide, 23-26 pts. wt. butanone, 1-3 pts. wt. antimony trioxide, 15-18 pts. wt. flame retardant (A), 17-19 pts. wt. flame retardant (B), 7-11 pts. wt. lubricant, 5-8 pts. wt. antioxidant and 5-7 pts. wt. chain extender. USE - Thermoplastic polyurethane elastomer. ADVANTAGE - The environmentally-friendly thermoplastic polyurethane elastomer has excellent flame retardance, tensile strength, elongation at break, mechanical property, wear resistance, tear resistance, hydrolysis resistance and aging resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of thermoplastic polyurethane elastomer, which involves heating thermoplastic polyurethane, adding graphene oxide, stirring, heating, adding p-phenylene diisocyanate, stirring, adding remaining raw materials, mixing, curing, extruding, water cooling, drying, and pelletizing.
