Texin® 950 U
TPU(热塑性聚氨酯)
科思创 (原拜耳)(Covestro)
产品描述
Texin 950U resin is a polyether-based thermoplastic polyurethane with a Shore hardness of approximately 50D. It can be processed by injection molding or extrusion.
In addition to inherent resistance to salt water stress cracking, hydrolysis, Texin 950U resin offers outstanding abrasion resistance, impact strength, toughness, and flexibility. It is also stabilized against degradation due to heat and UV exposure. Applications include gasketed hose, tubing, shoe inserts, connectors, belting, and miscellaneous molded articles. In addition, Texin 950U natural color resin is listed under NSF stanard 61 for use in potable water applications. As with any product, use of Texin 950U resin in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
