Fumed silica

Product Name

^{Name: Fumed silica}

Product Overview

^{Fumed silica is an extremely important high-tech ultra-fine inorganic new material. Fumed silica is mainly prepared by chemical vapor deposition (CVD) method, also known as pyrolysis method, dry method or combustion method. Its raw materials are generally silicon tetracloride, oxygen (or air) and hydrogen, reacted at high temperature. Fumed silica can be divided into hydrophilic type and hydrophobic type, this product is hydrophilic type.}

^{Product Features}

^{1）Chemical inertia: Fumed silica is chemically inert and is not easy to react with other substances, which makes it stable in a variety of applications.}

^{2）Surface hydroxyl: the surface contains silanyl and hydroxyl, these functional groups enable it to form chemical bonding with other materials, thus enhancing the properties of the material.}

^{Application Fields}

^{1）Rubber industry: as a reinforcing agent of silicone rubber, it can significantly improve the tensile strength, tear resistance and wear resistance of rubber products.}

^{2）Coating industry: used as a thickening agent of unsaturated resin, as well as the coating of anti-sink, thickening, anti-flow hanging AIDS.}

^{3）Plastic industry: as a plastic filling agent, it can improve the mechanical properties and processing properties of plastics.}

^{4）Ink industry: used as a thickener of ink, can improve the ink touch degeneration and stability.}

^{5）Other fields: it can also be used as metal soft abrasive, insulation and insulation filler, advanced daily cosmetics fillers and spraying materials, medicine, environmental protection and other fields of additives or catalyst carrier.}
