Wholesale Silicone Dioxide for Rubber as Reinforcement
Product:Silica,Silicone Dioxide,SiO2
CAS No.:7631-86-9
Apperance: white powder
Function of silica in rubber products:
(1) Reinforcement: the tear strength of the compound reinforced with white carbon black can be significantly improved. Therefore, about 10-25 parts of white carbon black are usually added to the tread rubber of many large-size tires to significantly improve the performance of anti cutting, flower and crack of tire tread. It should be noted that when using silica to improve the tear strength of rubber products, the wear resistance of rubber will decrease with the increase of the amount of silica. The amount of silica should be reasonably controlled.
(2) Adhesion: silica has active silanol on the surface, which is an important part of m-methyl-white adhesion system. In actual production, m-nail white bonding system can significantly improve the bonding strength between rubber and skeleton materials (including cotton, nylon, polyester, steel wire, etc.).
