White carbon black
【White carbon black】alias Hydrated Silica; Silicondioxidehydrate
【Molecular formula】SiO2.nH2O
【Physicochemical property】It is small amorphous powder, chemical stability, heat is not easy to break down, do not burn large specific surface area, electrical insulation and strong.
【Use】White carbon black,Its whiteness, fill in the rubber compound can improve the physical property, has become the best white instead of black reinforcing filler. In addition to rubber, but also widely used in paints, inks, feed, pesticides, fire extinguishing agents, and paper.
