Fumed silica, also known as fumed silica, is a kind of fine nano-scale amorphous silica obtained by high temperature hydrolysis of halosilane in hydrogen-oxygen flame. It has small particle size, uniform particle size distribution, large specific surface area and high surface activity. Fumed silica is widely used in polymer composite materials, silicone rubber, coatings, electronic packaging materials, colloidal batteries, ceramics, plastics, glass fiber reinforced plastic, sealants, paper, food, cosmetics, gel coat resin, chemical mechanical polishing and other industries, can play a reinforcing, thickening, thixotropic, extinction and other roles.
