Porous, non-toxic tasteless no pollution, high temperature resistance. At the same time it has chemical inertness and special thixotropic properties significantly improved the tensile strength of the rubber products, tear resistance and wear resistance, improved rubber strength increased several times. Rheology and thixotropy control system, liquid adhesive, polymer, used as anti settling, thickening, anti sagging agent, reinforcing HCR and RTV-2K silicone rubber, can be used to regulate the free flow and as anti caking agent to improve the properties of powder and so on.
