Thermoplastic elastomer TPU has a wide range of hardness: by changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and with the increase of hardness, the product still maintains good elasticity and wear resistance. TPU has high mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption performance. Excellent cold resistance: TPU has a relatively low glass transition temperature and maintains good elasticity, flexibility and other physical properties at minus 35 degrees. TPU has good processing properties: TPU can be processed by common thermoplastic processing methods such as injection molding, extrusion, calendering and the like. At the same time, TPU can be processed together with certain polymer materials to obtain polymer alloys with complementary properties. TPU is resistant to oil, water and mold.

TPU is a thermoplastic polyurethane, which has a polyester type and a polyether type. It has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity. It is used in the fields of daily necessities, sporting goods, toys, decorative materials, etc. Widely used, halogen-free flame retardant TPU can also replace soft PVC to meet the environmental requirements of more and more fields.
