Product Description
Introduction:
Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments.
Fumed silica includes Hydrophilic type and Hydrophobic type. And each type has many grades, no matter what grade you used before, we will provide the suitable grade of fumed silica to you.
Its appearance is white powder. Native particle size ranges from 5nm-40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.
Properties:* Reinforcing filler in elastomers
