Fumed Silica By Shanghai Qunyue Chemical Co.,ltd

These Fumed Silica is a hydrophilic fumed silica with a specific surface area of 200m2/g, It is a kind of high purity white colloidal powder.
Using the chlorosilane burning in hydrogen and oxygen flame at high temperature to get fumed silica (also named carbon black) is a white, non-toxic, tasteless, amorphous inorganic chemical product. By adjusting the technological conditions, QUNYUE enterprise production of the original size 7a 40nanometers,with a specific surface area between 70---400m2/g.Because of its small particle size a bigger surface area a more activate surface characteristic ,in rubber a coatinga adhesivea painta printing ink a plastica cosmetics as well as agriculturea medicine and other fields has the widespread application, to have a good reinforcementa thickeninga absorbing the transparencea anti-UVa sterilization and so on .
