White Carbon Black (Silicon Dioxide) for Rubber and Chemical Materials
Molecular formula: SiO2. NH2O sixty, molecular weight, have very strong activity and adsorption, appearance is white powder or granule, melting point 1750 ℃, the high temperature not decompose, insoluble in water and common acid, soluble in hydrofluoric acid and caustic, non-toxic, high insulation.
White carbon black is a good reinforcing agent and filling agent, widely used in tires, conveyor belt, rice milling rubber roller, textile rubber ring rubber roller, shoes and other industries; Can obviously improve the physical properties of the rubber, has become the best instead of carbon black reinforcing white packing. In addition, also widely used in fire fighting, pesticides, paper making, feed, printing ink, paint, triangle tape etc enterprise field.
