Silica is a white powder X- ray amorphous silica and silicates, collectively, silica, mainly refers to precipitated silica, fumed silica, silica gel and silica ultrafine airgel, silica sales Which is good, as well as powdered synthetic aluminum silicate and calcium silicate. Silica is a porous material, the composition can be used SiO2 · nH2O, where nH2O exists in the form of surface hydroxyl groups. Can be dissolved in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, non-flammable, tasteless, odorless, has good electrical insulation properties. In the normal tire add a certain amount of silica can improve the life of the tire. According to the former West Germany, a company tire compounds study results showed that, if equipped with 10 to 20 parts silica can improve the bonding properties and tear resistance, the tire mileage increase, while enhancing the tire on the road grip facilitate safe driving.
