Polyurethane TPE

作者: 殊鸿小编点击: Release Date: 2018-06-14 Author: Hong Shu Xiao Bian click:

Polyurethane TPE is a thermoplastic polyurethane rubber which is composed of urethane hard segments that react with isocyanate and polyester or polyether soft segments. The TPU has excellent mechanical strength, abrasion resistance, oil resistance and resistance. Flexibility, especially abrasion resistance, is most prominent. Disadvantages are poor heat resistance, hot water resistance and compression resistance, the appearance is easy to turn yellow, and the mold is sticky during processing. Currently in Europe and the United States and other countries are mainly used to manufacture ski boots, hiking boots and other sports goods, and a large number of production of various sports shoes, travel shoes, a lot of consumption. TPU can also produce parts such as automobiles, machinery, watches and clocks by injection molding and extrusion, and is widely used in high-pressure hoses (outer rubber), pure rubber hoses, sheets, transmission belts, conveyor belts, wires and cables, and tapes. Among them, injection molding accounts for more than 40%, and extrusion molding is about 35%.

In recent years, in order to improve the processing performance of TPU, many new easy-to-process varieties have appeared. If it is suitable for two-color molding, it can increase the transparency, high flow and high recycling of TPU for shoemaking, which can improve the processing and production efficiency. Plastic-free, low-hardness, easy-to-process TPU for the manufacture of transparent hoses. It is used for large parts such as automobile bumpers and reinforced TPU reinforced with glass fiber to improve rigidity and impact. In particular, the reactive component is added to the TPU. After thermoplastic molding, the incomplete IPN (the IPN formed by the cross-linked polymer and the non-cross-linked polymer) is developed rapidly by ripening. This IPN TPU further improves the physical and mechanical properties of the TPU. In addition, the TPU / PC blended alloy TPU improves the safety performance of automobile bumpers. In addition, there are high-permeability TPUs and conductive TPUs, and TPUs dedicated to biological, magnetic tape, safety glass, etc. have appeared.
