TPU (Thermoplastic polyurethanes) is called thermoplastic polyurethane elastomer rubber. Elastomer refers to a polymer material with glass transition temperature lower than room temperature, elongation at break > 50%, and better recovery after external force is removed.

The main characteristics of TPU are:

Wide range of hardness: By changing the ratio of the reactive components of TPU, products with different hardness can be obtained, and with the increase of hardness, the products still maintain good elasticity and wear resistance.

High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.

Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees.

Good processing performance: TPU can be processed by common thermoplastic material processing methods, such as injection molding, extrusion, calendering, etc. At the same time, co-processing of TPU and certain polymer materials can obtain polymer alloys with complementary properties.

Moreover, TPU is oil-resistant, water-resistant, mold-resistant, and has good recycling properties.
