Shanghai Daoqin Plastics Co., Ltd.

1. wear resistance can

　　当材 material in use process in 常常受冲突, abrasion, and other machine 械效果, 会引起 its outer table/sheet abrasion loss, 因而资 material abrasion consumption property non important. TPU plastics raw materials wear resistance can excellent 良, relatively 天然橡胶 wear resistant above, is wear resistant products 首选 材 material 之一.

　　2. tensile property can

　　 tensile strength can high 达70MPa, fracture elongation can high 达1000%.

　　3. property can

　　 elastomer in application is generate expand large from make bad is 撕裂, strong/high degree table/sheet 达 就 is material resistant function can force; generally 而言TPU tool has relatively high resistant can force, strong/high degree and commonly used plastics comparison is non excellent.

　　4. property can

　　 very more plastics material in heavy cycle property force function lower easy generate fracture, TPU products in different ring lower can maintain resistant features, is polymer/macromolecule material in most selection 之一.

　　5. resistant high temperature and resistant oxidation property can

　　 generally plastics raw materials long in 70摄氏 degree above ring lower easy oxidation,TPU resistant oxidation can force good; generally 而言TPU resistant temperature property can 达120摄氏 degree.

　　6. oil resistant and resistant product property can

　　TPU is types strong/high property polymer/macromolecule material, and non property material hydrophilic and property very small, in material 油(如煤油, 汽油) and machine 械油(如 liquid pressure 油, machine 油, lubricated and other) in basic 几乎不受侵蚀; in this 里, TPU plastics raw materials product in also polyester series product oil resistant property relatively 佳;TPU film and sheet/slice for/regarding 油脂 体积变化 very small, resistant strong/high degree ratio 原初始 value more high; value attention/notes is in material in if has a small amount of water separation 时, for film material property generate different degree negative effect/influence.

　　7. low temperature property can

　　TPU has non good low temperature resistance property can, usually can to -50摄氏 degree, can generally pvc因 low temperature 脆化而无 method application field/area, especially combined use in belt/tape related types type products.

　　8. material property can

　　TPU tool has good material versus property, 无毒, 无 敏 reaction property, local property, hot property, therefore application in medical, and other related product and 运动, device upper.

今天, tpu already by widely used in: footwear materials, formed 衣, gas toys, water upper and water lower sports equipment, medical device 材, device 材, automotive base/seat material, 雨伞, 皮箱, and other.
