The main characteristics of TPU are:
1. Wide hardness range: By changing the ratio of TPU reaction components, products with different hardness can be obtained, and as the hardness increases, the products still maintain good elasticity and wear resistance. The rigidity of TPU can be measured by its elastic modulus. The elastic modulus of rubber is usually between 1-10Mpa, TPU is between 10-1000Mpa, and plastics such as nylon, ABS, PC, POM are between 1000-10000Mpa. The hardness range of TPU is quite wide, ranging from Shore A 60 to Shore D 85, and it has high elasticity throughout the entire hardness range.
2. High mechanical strength: TPU products have outstanding load-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 minus 35 degrees Celsius. TPU has flexibility over a wide temperature range of -40~120 ℃, without the need for plasticizers.
4. Good processing performance: TPU can be processed using common thermoplastic material processing methods, such as injection molding, extrusion, rolling, and so on. At the same time, TPU can be processed together with certain polymer materials to obtain polymer alloys with complementary performance.
5. Resistant to oil, water, and mold. TPU has good resistance to oils (mineral oils, animal and vegetable fats, and lubricants) and many solvents.
6. Good recyclability.
7. TPU also has good weather resistance and excellent resistance to high-energy radiation.
As is well known, TPU has excellent wear resistance, tear resistance, and flexural strength; High tensile strength, high elongation, and low long-term compression permanent deformation rate are all significant advantages of TPU.
