中文简体1、 TPU introduction
TPU name is thermoplastic polyurethane elastomer rubber. It has a wide hardness range (60ha-85hd), wear resistance, oil resistance, transparency and good elasticity, and is widely used in daily necessities, sports goods, toys, decorative materials and other fields. TPU not only has excellent characteristics of high tension, high tension, toughness and aging resistance, but also is a mature environmental protection material.
2、 TPU characteristics
1. Wide range of hardness: products with different hardness can be obtained by changing the proportion of each reaction component of TPU, and with the increase of hardness, the products still maintain good elasticity and wear resistance.
2. High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.
3. Outstanding cold resistance: the glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at - 35 ℃.
4. Good processing performance: TPU can be processed by common processing methods of thermoplastic materials, such as injection molding, extrusion, calendering, etc. At the same time, TPU and some polymer materials can be processed together to obtain polymer alloys with complementary properties.
3、 TPU application field
TPU has been widely used in: smart wear (including watch case, watch strap, bracelet, wristband), daily necessities, sports goods, toys, shoes, umbrellas, suitcases, bags and other fields.
