Appearance: Loose white powder
Properties: Fumed silica (commonly known as fumed white carbon black) which is made through using chlorosilane with pyrohydrolysis in oxyhydrogen flame, is a kind of white amorphous inorganic fine chemical products without poison and taste. By adjusting technological conditions, fumed silica product can be produced, whose primary particle size is from 7nm to 40nm, and whose specific surface area is form 50m2/g to 400m2/g. Due to its small particle size, large specific surace area and strong surface activity, its widely used in rubber, coatings, adhesives, paints, inks, plastics, cosmetics, agriculture, medicine and other fields. It has so many functions, such as reinforcing, thickening, thixotropic, matting, uvioresistant, fungiciding and so on.
Application: It is mainly used in feed additive, vitamin E and other industries. It is favorable carrier for feed flavor enhancement, mildew-proof agent, antioxidant, allicin, swelling agent, caking inhibitor, premix compound, microelement, vitamin and other products.
