Thermoplastic polyurethane elastomer (TPU) is a kind of elastomer which can be plasticized by heating and dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance and good processability, and is widely used in national defense, medical care, food and other industries.
The main features of TPU are:
Wide hardness range: products with different hardness can be obtained by changing the proportion of TPU reaction components, 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.
