Description of Fumed Silica

Fumed silica, molecular formula is SiO2. White fluffy powder, porous, non-toxic, tasteless and pollution-free, high temperature resistant. At the same time it has the chemical inertness and special thixotropy can significantly improve the tensile strength, tear resistance and wear resistance of rubber products, rubber improved strength increased by tens of times. It can be used as rheological and thixotropic control for liquid systems, adhesives, polymers, etc., as an anti-sink, thickening, anti-sagging additive, reinforcement for HCR and RTV-2K silicone rubber, used to regulate free flow and as an anti-caking agent to improve powder properties, etc.
