What material is tpu?

TPU: The name is thermoplastic polyurethane elastomer rubber (it is a polymer material formed by the reaction of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyol and low molecular polyol (chain extender) * * *), which is referred to as polyurethane for short. Excellent performance, it can be softened at a certain temperature, but it can remain unchanged at room temperature. TPU can be used where PVC and PU can be used, which can be said to be the most ideal material to replace PVC and pu. It is called green environmental protection material internationally.

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.

Performance summary ..... It has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and weather resistance that other plastic materials can't match. At the same time, it has many excellent functions such as high waterproof, moisture permeability, wind resistance, cold resistance, antibacterial, mildew resistance, warmth retention, ultraviolet resistance, energy release and so on.
