Covestro Texin® RxT65D Thermoplastic Polyurethanes (TPU)
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	Characterization: Texin RxT65D resin is an aromatic polyether-based thermoplastic polyurethane. It can be processed by injection molding, extrusion or blow molding. Properties / Applications: Texin RxT65D offers outstanding abrasion resistance, impact strength, toughness and flexibility. It also exhibits excellent hydrolytic stability. Typical medical applications include anesthetic connectors, catheters, flexible tubing, film, seals and gaskets and extruded profiles. As with any product, use of Texin RxT65D resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
