What is fumed silica and what it has?

Fumed silica (gas phase white carbon black) is one of the most important high-tech ultra-fine inorganic new materials. It is porous, non-toxic, tasteless, non-polluting and high temperature resistant. At the same time, its chemical inertness and special thixotropic properties significantly improve the tensile strength, tear resistance and wear resistance of rubber products, and the strength of rubber is improved by several tens of times. Rheological and thixotropic control of liquid systems, adhesives, polymers, etc., used as an anti-settling, thickening, anti-sagging additive, HCR and RTV-2K silicone rubber reinforcement, can be used to regulate free flow And as an anti-caking agent to improve powder properties and the like. Gas phase titanium dioxide, fumed alumina, mainly involved in applications: adhesives, coatings, paints, inks, batteries, toners, pharmaceuticals, food, plastics, paper, cosmetics, silicone rubber, defoamers, composites, feeds, etc. each field. The fumed silica is a white, non-toxic, odorless, amorphous inorganic fine chemical product. The atomic particle size is 7-40 nm, and the specific surface area is 70-400 m/g. It has good functions of strengthening, thickening, thixotropic, extinction, anti-ultraviolet and sterilization.

The particle size is small, so the specific surface area is large, the surface adsorption force is strong, the surface energy is large, the chemical purity is high, the dispersion performance is good, the thermal resistance, the resistance and the like have specific properties, and the superior stability, the reinforcing property, and the like Thickness and thixotropy are unique in many disciplines and fields and have an irreplaceable role. Nano-silica, commonly known as “ultra-fine white carbon black”, is widely used in various industries as an additive, catalyst carrier, petrochemical, decolorizing agent, matting agent, rubber reinforcing agent, plastic filling agent, ink thickener, metal softness. Polishing agent, insulating and insulating filler, advanced daily cosmetic filler and spraying materials, medicine, environmental protection and other fields. It also provides new material foundation and technical guarantee for the development of related industrial fields.
