Precipitated silica is one of the most important high-tech ultra-fine inorganic new materials. Due to its small particle size, it has large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, resistance and other aspects of special performance. The fumed white carbon black is used in rubber, tires industries.
