Property: White carbon black, the formal name is hydrated silica dioxide by sedimentation, white color, multi finestra powder or floccules powder with highly dispersion, high specific surface area, soluble in caustic soda and hydrofluoric acid, insoluble in other acids and solvent, high temperature resistant without combustion, good electricity insulation, good appetency to fiber, rubber and plastic, is widely used in industries. The white carbon black are also made with sedimentation process, precisely controlled, the products is even and superfine in particle size with perfect specific surface area, high dispersion and extreme strong absorption ability. White carbon black belongs to non-active chemicals, when used in the polymers such as rubber, the physical reaction happens, then the particle of white carbon black make web structure with rubber molecular chain naturally. The white carbon black produced by our company use super quality raw materials, with advanced equipment and strictly process control, the performance specification meet and superior than the standard HG/T3061-99, and can promise the client's products to be super quality.
