Shanghai Yuejiang chemical products Co., Ltd.   

Fumed silica fumed silica YJ968, YJ958, YJ2#, YJ4#, physical and chemical properties: Yue Jiang card - fumed silica has a small particle size, high structure, large specific surface area, with reinforcing performance is very strong, the silica surface silanols (Si-OH) can be physical or chemical combination and molecular silicon rubber forming, silicone rubber molecules adsorption layer formed on the surface of silica, the three-dimensional network structure composed of silica particles and rubber molecules into one, so as to achieve the role of reinforcement. After the silicone rubber by gas phase silica reinforcement, strength of highest
