Silicone rubber alloy A-S/TPU 1175

Product characteristics


A-S/TPU 1175 is an alloying material with stable island structure, which uses dynamic vulcanization process to evenly disperse silicone rubber in TPU with micrometer particle size. The unique molecular structure of silicone rubber makes it have good compatibility with TPU substrate. Different from the traditional silicone masterbatch in the form of linear dispersion of silicone oil in the resin, granular silicone rubber in the alloy material is not easy to precipitated, no backsticking, the toughening effect is more obvious, break elongation and tear strength have been significantly improved, but also let the material has a good touch and skin friendly fruit. The presence of a large number of silicone rubber particles also improves the water resistance of the resin to a certain extent, and because the surface energy of the silicone rubber is relatively low, the alloy material has good easy to clear.
