Fumed silica is the superfine micro-nano fine chemical item, which is divided into hydrophilic variety and hydrophobic kind in accordance with their distinct surface treatment options. Its visual appeal is white powder. Native particle size ranges from 5nm to 40nm, with substantial features of thixotropy, reinforcing, thickening and filling. Therefore, it is extensively utilized in the EPT of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, meals and so forth.
