TPU(热塑性聚氨酯)
科思创 (原拜耳)(Covestro)
产品描述
Texin DP7-1049 resin is an aromatic polyether-based thermoplastic polyurethane with a Shore hardness of approximately 45D. It can be processed by injection molding, extrusion, or blow molding.
Texin DP7-1049 resin exhibits inherent resistance to hydrolysis. It also provides clarity and outstanding abrasion resistance, impact strength, toughness, and flexibility. Typical applications include boots, nonregulated animal identification tags, seals, pads, tubing, cable jacketing, sheet, and profiles. As with any product, use of Texin DP7-1049 resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
