Covestro Texin® 970 U Thermoplastic Polyurethanes (TPU)
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	Texin 970U resin is an aromatic polyether-based thermoplastic polyurethane with a Shore hardness of approximately 70D. It can be processed by injection molding, extrusion, or blow molding. Properties / Applications: Texin 970U resin offers exhibits excellent tensile and tear properties, high stiffness characteristics, good resistance to fuels and oils, and inherent resistance to hydrolysis. It is stabilized against degradation due to heat and UV exposure. Typical applications include industrial screens and casters, bushings, housings, agricultural equipment components and marine equipment. Information provided by Covestro
