Carbon black is a black powdery substance formed by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions.
White carbon black is the general name for white powdery X-ray amorphous silicic acid and silicate products, mainly refers to precipitated silica, fumed silica, ultrafine silica gel and aerogel, also including powdered Synthetic aluminum silicate and calcium silicate, etc. White carbon black is a porous material, and its composition can be expressed as SiO2·nH2O, where nH2O exists in the form of surface hydroxyl groups. Soluble in caustic alkali and hydrofluoric acid, but insoluble in water, solvents and acids (except hydrofluoric acid). It is high temperature resistant, non-flammable, tasteless, odorless, and has good electrical insulation.

White carbon black is used in colored rubber products to replace carbon black for reinforcement to meet the needs of white or translucent products. White carbon black also has super strong adhesion, tear resistance, heat resistance and anti-aging properties, so it can also replace part of carbon black in black rubber products to obtain high-quality rubber products, such as off-road tires, engineering tires, etc. Radial tires, etc.
