Fumed silica (white carbon black) M-5 is hydrophilic products, which are mainly used silicone rubber (HTV, RTV), resin coatings, paints, inks, electronics, paper, pharmaceutical, cosmetics and painting, toothpaste, adhesives, plastics and other industries production, its characteristics is a good anti-settling, anti-sag, thixotropic thickening, anti-settling and improve the dielectric properties, to promote the free flow of self-cleaning, etc., is an excellent effect free-flow aids, plus a system of positive and negative control agents, including sexual component (catalyst) carriers, granulating aids, processing aids, anti-caking agents, stabilizers. Since fumed silica particles having unusual characteristics , which is considered a share and the industry. The small particle size of the fumed silica, a huge surface area. High purity and its tendency into a chain, making it sui generis. Fumed silica of the role of performance, the most important is the damage of the structure and to change the flow characteristics of the product are alternately formed by the existence of the mesh structure and the magnitude of the force caused depending on the cut, and thus can Configuring the stringent requirements to control liquidity person. Another unique role fumed silica, is the ability to simultaneously improve several different properties of the same products, and the use of other single substance, or even several substances are difficult to achieve this effect. When using fumed silica in coatings, adhesives, paintings cosmetics, inks, plastics, and rubber and other products, can simultaneously improve or get thickening, thixotropic, solid suspension and transparency. Fumed silica can promote dry powder, granular substance and the substance of the free flow of pills, this performance is extremely useful in the food, cosmetics and various chemical industrial products.
