Texin® 985AU
TPU(热塑性聚氨酯)
科思创 (原拜耳)(Covestro)
产品描述
Texin 985AU resin is an aromatic polyether-based thermoplastic polyurethane with a Shore hardness of approximately 85A*. It can be processed by injection molding, extrusion, or blow molding.
Properties / Applications:
Texin 985AU resin offers good clarity and outstanding abrasion resistance, impact strength, toughness, and flexibility. It is stabilized against degradation due to heat and UV exposure. It also exhibits excellent hydrolytic stability, as well as excellent microbial resistance. Typical applications include belting, hose, cable jackets, hose jackets, seals and gaskets, athletic soles, casters, mine screens, tubing, film, and extruded profiles. Texin 985AU natural color resin is listed under NSF Standard 61 for use in potable water applications. As with any product, use of Texin 985AU resin in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
