Carbon black is a black powdery substance in which hydrocarbons are incompletely burned or pyrolyzed in the gas phase under strictly controlled process conditions.
Silica is a general term for white powdered X-ray amorphous silicic acid and silicate products. It mainly refers to precipitated silica, fumed silica, ultrafine silica gel and aerogel, and also includes powder. Synthesis of aluminum silicate and calcium silicate. Silica is a porous substance whose composition can be represented by SiO2•nH2O, wherein nH2O is in the form of a surface hydroxyl group. Soluble in caustic and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-combustible, odorless, odorless, and has good electrical insulation.
White carbon black is used in color rubber products to reinforce carbon black to meet the needs of white or translucent products. White carbon black also has superior adhesion, tear resistance and heat and aging resistance, so it can replace some carbon black in black rubber products to obtain high quality rubber products, such as off-road tires, engineering tires, Meridian tires, etc.
