Today, Xiaobian will show you the difference between Xinda Chemical white carbon black and carbon black. I hope it will help you.


White carbon black and carbon black are completely two substances, but they can be replaced in some aspects. 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 of white powdered X-ray amorphous silicic acid and silicate products, mainly refers to ultra-fine silica, fumed silica, ultra-fine silica gel and aerogel, and also includes powdered synthetic aluminum silicate and calcium silicate.


Silica is a porous material, whose composition can be expressed by SiO2 · nH2O, in which nH2O exists in the form of surface hydroxyl. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non combustible, tasteless, odorless, with 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 adhesion, tear resistance, heat resistance and aging resistance, so it can also replace some carbon black in black rubber products to obtain high-quality rubber products, such as off-road tires, engineering tires, radial tires, etc.
