Because of its nano-effects, in the material the fumed silica exhibits excellent properties of reinforcing, thickening, thixotropic, insulation, matting, anti-sagging, which are widely used in the silicone rubber (polyester plastics, sealing materials,etc.), siliconeglue (adhesives,paints,coatings,etc.)and high-performance fibers, new synthetic unsaturated resin, electric insulation, inks, pharmaceuticals, paper, food, cosmetics, chemical mechanical polishing, etc., to be known as the "industrial MSG". 收起
