TPU(热塑性聚氨酯)
科思创 (原拜耳)(Covestro)
产品描述
Texin 985AR resin is an aromatic polyether-based thermoplastic polyurethane; it can be processed by injection molding or extrusion.
Properties / Applications:
Texin 985AR resin offers outstanding abrasion resistance, impact strength, toughness, and flexibility. It also exhibits excellent hydrolytic stability. Texin 985AR 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 other applicable regulations. In addition, Texin 985AR natural color resin is listed under NSF standard 61 for use in potable water applications.
Applications include belting, hose, seals and gaskets, tubing, cable jackets, hose jackets, athletic soles, grips, mine screens, film, and extruded profiles. As with any product, use of Texin 985AR resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
