characteristic
The main characteristics of TPU are: wide hardness range: products with different hardness can be obtained by changing the proportion of various reaction components of TPU, and with the increase of hardness, their products still maintain good elasticity and wear resistance. High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption. Outstanding cold resistance: the glass transition temperature of TPU is relatively low, and it still maintains good physical properties such as elasticity and flexibility at MINUS 35 degrees. Good processability: TPU can be processed by common processing methods of thermoplastic materials, such as injection molding, extrusion and calendering. At the same time, TPU can be processed with some polymer materials to obtain polymer alloys with complementary properties. Oil-resistant, waterproof and mildew-proof. Good recovery performance.

It has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency and good elasticity, and is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Halogen-free flame retardant TPU can also replace soft PVC to meet the environmental protection requirements in more and more fields. There are many TPU brands with uneven quality. When selecting TPU, it is best to go through detailed evaluation and demonstration, otherwise the best cost-effective result cannot be obtained. TPU is a substance that softens at a certain temperature, but remains unchanged at room temperature. When used in shoes, it has many functions of stability and support. TPU, also known as polyurethane rubber, is a kind of polyurethane, which is a relatively new product in China and widely used in footwear, pipe ... and other industries.
