Product Description
Silicon Dioxide
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.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 of Fumed Silica Dioxide:
Reinforcing filler for elastomer, adhesives & sealants · High hydrophobicity and stable thixotropy · Anti-settling and anti-sagging agent in coatings and printing ink · Improving dispersion and stability of pigment · Rheological control for adhesives & sealants · Free flow aid and anti-caking aid for powders.
