Silica gel CAS NO.112926-00-8

It has small particle size, large specific surface area, high structural property, and strong reinforcing properties. The silanol group (SIOH) on the surface of silicon dioxide can form a physical or chemical combination with silicone rubber molecules, forming a silicone rubber molecular adsorption layer on the surface of silicon dioxide, forming a three-dimensional network structure of silicon dioxide particles and rubber molecules, so as to achieve the reinforcing effect. After reinforced by fumed silica, the strength of silicon rubber can be increased by up to 40 times. Application range: silicone rubber, tablets, cosmetics.
