Covestro Texin® 990 R Thermoplastic Polyurethanes (TPU)
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	Texin 990R resin is a polyether-based thermoplastic polyurethane with a Shore hardness of approximately 90A. It contains an internal mold release additive. This resin can be processed by injection molding or extrusion. Properties / Applications: Texin 990R resin offers outstanding abrasion resistance, impact strength, toughness, and flexibility. It also exhibits excellent hydrolytic stability, and exceptional mold release characteristics. Texin 990R natural color resin complies with FDA food-contact regulations 21 CFR 177.1680 (Polyurethane Resins) and 177.2600 (Rubber Articles Intended for Repeated Use), subject to the limitations of these and any other applicable regulations. It is also listed under NSF Standard 61 for use in potable water applications. Typical applications include belting, hose, seals and gaskets, tubing, cable jackets, hose jackets, athletic soles, casters, film, extruded profiles, and miscellaneous molded articles.
