Molecular formula of fumed silica :SiO2, white fluffy powder, porous, non-toxic, tasteless and pollution-free, high temperature resistance. 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 increased tens of times after improvement. Rheological and thixotropic control of liquid systems, adhesives, polymers, etc., used as an anti-sink, thickening, anti-flow agent, reinforcement of HCR and RTV-2K silicone rubber, used to regulate free flow and as an anti-caking agent to improve powder properties, etc.
CAS No.:112 945-52-5
