TPU(Thermoplastic polyurethanes)名称为热塑性聚氨酯弹性体橡胶。主要分为有聚酯型和聚醚型之分,它硬度范围宽(60HA-85HD) 耐油,透明,弹性好,在日用品、体育用品、玩具、装饰材料等领域得到应用,无卤阻燃TPU还可以代替软质PVC以满足越来越多领域的环保要求。
所谓弹性体是指玻璃化温度低于室温度,断裂伸长率>50%,外力撤除后复原性比较好的高分子材料。聚氨酯弹性体是弹性体中比较一大类,聚氨酯弹性体的硬度范围很宽,性能范围很宽,所以聚氨酯弹性体是介于橡胶和塑料的一类高分子材料。
TPU应用范围用于手机套,手机配件,表带,鞋材,鞋材配件,各种脚轮,潜水眼镜,滑雪眼镜,等眼镜配件,密封圈. 密封件管材。油管气动管。线材,电线电缆,水管,弹性丝,弹簧线,弹簧管,波纹管汽车配件,电动工具配件,雾面线外皮包胶贴胶,变速杆球柄、滚轴、连轴器、鞋跟、齿轮儿童玩具,耐油性、耐热性、耗耐寒性
