    TPU是Thermoplastic polyurethane的縮寫,化學名稱為熱塑性聚氨酯彈性體,是聚氨酯的一種,也就是說它是PU家庭的成員之一,它介于橡膠與塑料之間的一種新型高分子合成材料。

    TPU is the abbreviation of Thermoplastic polyurethane. Its chemical name is thermoplastic polyurethane elastomer. It is a kind of polyurethane. That is to say, TPU is a member of PU family. It is a new type of polymer synthetic material between rubber and plastics.


    Thermoplasticity? It can repeatedly soften or change plastic materials at a certain temperature, but it can keep its shape unchanged at room temperature. It can be used to produce injection, extrusion and blow-moulding products, such as casters, heels, handles, sports equipment, garment accessories, sealing materials, etc.



    Elastomer? Hardness range is very wide, performance range is very wide, can be well combined with metal and concrete and other materials, such as the black technology picture above the general effect, has a good resilience. It can be used for spraying automobile chassis, etc. It can effectively reduce the damage caused by bumping.


    TPU is a granular material. The hardness range of TPU is wider in the product hardness range of 65A-85D. The color is natural, transparent and highly transparent. It has the characteristics of high strength, good toughness, abrasion resistance, cold resistance, oil resistance, water resistance, aging resistance and climate resistance that other plastic materials can not match. At the same time, it has many excellent functions such as high waterproof and moisture permeability, wind resistance, cold resistance, antimicrobial, mildew resistance, warmth retention, ultraviolet resistance and energy release.


    TPU and PU are essentially made up of the same material. The above characteristics are both mechanical and physical properties. The characteristics of different formulations in actual production are also different.
