TPU,全称为热塑性聚氨酯弹性体(Thermoplastic Polyurethane Elastomer),是一种由高分子量聚酯或聚醚与含2~12直链碳原子的二醇通过二异氰酸酯化学结构连接而成的(AB)n型嵌段线性聚合物。这种材料具有独特的分子间氢键交联或大分子链间轻度交联的特性,使得TPU在加热后可以塑化,在溶剂中可以溶解,冷却后能够恢复其原有的固体性能。TPU的这些特性使其在多个领域中得到广泛应用,包括但不限于鞋材、医疗、食品包装、国防、汽车部件等
Texin RxT85A resin is an aromatic polyether-based thermoplastic polyurethane. It can be processed by injection molding, extrusion or blow molding.
Properties / Applications:
Texin RxT85A 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, the use of Texin RxT85A resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
Texin®热塑性聚氨酯架起橡胶与塑料之间的桥梁。从柔韧到坚硬——这种材料提供各种硬度的品级。Texin® TPU的很多品级符合FDA食品接触材料的规定,多个品级满足FDA修订版ISO 10993-1测试对生物相容性的要求。
科思创Texin®TPU树脂为设计师提供了适用范围广泛的通用解决方案。典型用途包括脚轮、电动工具、体育用品、医疗设备和各种挤出薄膜、板材和型材应用。Texin®是一种极其坚固的高强度抗拉材料,具有出色的抗撕裂强度,良好耐受磨损、燃料和油脂,因此可满足各种不同的应用需求。灵活而有弹力,它还具有极强的低温灵活性和抗挠曲疲劳性,对各种基材具有良好的附着力,肖氏硬度在60 A至85 D之间。与Desmopan®结合使用,Texin®树脂可以很容易地粘接到各种基底,从而提供一种柔软的触感。
