Performance benefits

The versatility of our fumed silica is related to its wide range of surface areas and aggregate structure, both of which lead to unique performance benefits, including:

  • Anti-settling, thickening, and sag resistance
  • Scratch and abrasion resistance
  • Free-flow and anti-caking
  • Corrosion resistance
  • Enhanced absorbency
  • Reinforcement

Fumed silica is classified into 2 types:

  • Hydrophobic fumed silica

Be applied as a thickening and thixotropic agent in many organic systems, e.g. in unsaturated polyesters, coatings, printing inks, adhesives, cosmetics, and others. It is used as a reinforcing filler in elastomers, mainly silicone elastomers. Hydrophobic fumed silica acts as a free flow additive in the production of technical powders, in food and feed, and in pharmaceutical products.

  • Hydrophilic fumed silica

Be applied as a thickening and thixotropic agent in coatings, printing inks, adhesives, cosmetics, and others. It is used as a reinforcing filler in elastomers, mainly silicone elastomers. Hydrophilic fumed silica acts as a free flow additive in the production of technical powders.
