THERMOPLASTIC POLYURETHANE COMPOSITION

摘要

A thermoplastic polyurethane composition includes a thermoplastic polyurethane (TPU) and a polyoxymethylene. The thermoplastic polyurethane composition comprises 50 to 95 parts by weight of the TPU and 5 to 50 parts by weight of the polyoxymethylene, per 100 parts by weight of the thermoplastic polyurethane composition. The thermoplastic polyurethane composition has an Izod notched impact of greater than 0.5 fflb/in at -40°C as determined by ASTM D256 10, Method A, and an elastic modulus of greater than 700 psi at 130°C as determined by ASTM D412. A fluid transfer tube is formed from the thermoplastic polyurethane composition.
