Covestro Texin® 255 Thermoplastic Polyurethanes (TPU)
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	Texin 255 resin is a polyester-based thermoplastic polyurethane with a Shore hardness of approximately 55D. It can be processed by injection molding; extrusion processes are not recommended. Properties / Applications: Texin 255 natural color resin complies with FDA food-contact regulations 21 CFR 177.1680 (Polyurethane Resins) and 177.2600 (Rubber Articles Intended for Repeated Use), for use in articles that contact food except articles used for packing or holding food during cooking, subject to the limitations of these and any other applicable regulations. Texin 255 resin offers excellent fuel and oil resistance, as well as outstanding abrasion resistance, impact strength, toughness, and flexibility. Typical applications include toplifts, seals, gaskets, sleeves, casters, and gears. Information provided by Covestro
