应用介绍
1.薄膜和片材(TPU具较好耐磨性、抗刺穿性、抗撕裂性、弹性、粘合性)(TPU薄膜应用在冬季服装、鞋类具有防寒、保暖、防水性能好等特性外还具有特别好的透气性)
2.管材(TPU具有高伸长率,良好耐水解和抗微生物性、耐油性、优异机械性能,如作消防水管内衬,输y油管气动软管等)
3.鞋底,鞋邦等鞋材料(TPU具有突出耐磨性、抗刮性、耐刺穿性、抗纵向弯曲强度和低温冲击强度,其耐撕裂性和抗裂纹传播性是所有塑料中最好的。如作溜冰、滑雪靴、运动鞋、特种功能鞋等)
4.电线、电缆、光缆护套(TPU具良好耐磨性、耐环境、耐候性、耐腐蚀性、绝缘性、弹性和低温柔韧性等)
5.拉链片、高档塑料表带、表壳以及潜水表、礼品表等系列(TPU具有高弹、耐折、耐水性好手感舒适等)
6.机械制品和其它应用(如制造汽车部件、机械轴承、滚轮、输送带、橡塑筛网、工业胶管,垫圈,密封圈,游泳镜,冲浪板,表带,动物标牌,电器零部件,涂料,粘合剂,纤维等.)
