QY200 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 7— 40nanometers, with a specific surface area between 70---400m2/g. Because of its small particle size , bigger surface area , more activate surface characteristic , in rubber , coating, adhesive, paint, printing ink , plastic, cosmetics as well as agriculture, medicine and other fields has the widespread application, to have a good reinforcement, thickening, absorbing the transparence, anti-UV, sterilization and so on .
