What is TPU material?

TPU is short for Thermoplastic Urethane. It is called thermoplastic polyurethane elastomer in Chinese. Of course, it is also called polyurethane. But in fact, polyurethane is divided into many kinds of materials. Generally more people will call PU polyurethane. Therefore, there is no need to be so entangled on this issue, this article mainly wants to let you know what TPU is, want to know what TPU is composed of!

Thermoplastic polyurethane elastomer, as its name implies, is one of the types of polymers. Polymers are synthesized by the reaction of diisocyanate molecules such as toluene dihexacyanate (TDI) or diphenylmethane diisocyanate (MDI) with macromolecular polyols and low molecular polyols (also known as chain extenders). Material Science.

The molecular structure of TPU is composed of rigid blocks obtained by the reaction of MDI or TDI with chain extender, and flexible segments obtained by the reaction of diisocyanate molecules such as MDI or TDI with macromolecular polyols.

With superior high tension, high tension, toughness and aging resistance, it belongs to a relatively mature environmental protection material. At present, TPU material is used in almost all fields. Compared with other plastic materials, TPU material has higher strength and better toughness. It has high wear resistance, high temperature resistance, cold resistance, oil resistance and water resistance. TPU is different from other plastic materials because of its excellent functions such as anti-aging, anti-UV, high water-proof and moisture-permeability, wind-proof, cold-proof, anti-bacterial, mildew-proof and warm-keeping.
