Fumed silica (commonly known as fumed silica) is starting chlorosilanes in an oxyhydrogen flame high temperature hydrolysis and prepared. This product is wetted with water, can be dispersed in water, is a white, odorless, amorphous inorganic chemical products.Fumed silica, molecular formula: SiO2 white fluffy powder, porous, non-toxic tasteless non-polluting, high temperature. At the same time it has a chemically inert and special thixotropic properties can significantly improve the tensile strength of rubber, tear resistance and abrasion resistance, improved rubber strength is increased several times. Liquid systems, adhesives, polymers, rheology and thixotropy control, used as anti-settling, thickening, anti-sagging reinforcing additives, HCR and RTV-2K silicone rubber, can be used to regulate the free flow and as an anti-caking agent to improve powder properties, and so on. Fumed silica will send in handy in many printing inks, such as letterpress printing, gravure printing. It controls the flow to avoid gelling rate as to bring smeared, and thus bring perfect clarity.
