Vapor phase silica (fumed white carbon black) is one of the most important high-tech ultra-fine inorganic new materials. With CAS NO7631-86-9;white fluffy powder, non-toxic, tasteless and pollution-free.Because of its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion, thermal resistance, resistance and other aspects, has unique characteristics in many disciplines and fields with its superior stability, reinforcement, thickening and thixotropy, It plays an irreplaceable role. Nano-silica, commonly known as "ultra-fine silica", is widely used in various industries as an Food additive, catalyst carrier, petrochemical industry, decolorizing agent, matting agent, rubber reinforcing agent, plastic filler, ink thickener, metal soft polishing agent, insulation filler, advanced daily cosmetics filler and spraying materials, medicine, environmental protection and other fields. It also provides new material foundation and technical guarantee for the development of relevant industrial fields.
