Silica(Fumed silica) is a white, tasteless, no odor, no pollution of non-metal oxide. Because of its small particle size, specific surface area, high surface activity, in the material showed good reinforcing, increasing viscosity, thixotropy, insulation, extinction, anti-flow hanging properties, so it is widely application in pesticides, rubber, plastics, coatings, adhesives, seals, etc. high molecular industrial fields.
