Mitrious silica has small particle size, large specific surface area, high structure, and strong reinforcing properties, and the silanol group (Si-OH) on the surface of silica can form a physical or chemical combination with silicone rubber molecules, forming a silicone rubber molecule adsorption layer on the surface of silica, forming a three-dimensional network structure in which silica particles and rubber molecules are integrated, so as to achieve reinforcing effect. Silicone rubber is reinforced with fumed silica to increase its strength by up to 40 times.
Uses:
Inks, silicone rubber, tablets, cosmetics, plastics, coatings, pharmaceuticals and other fields.
