Fumed Silica is used as a thickener, a reinforcing filler or as a free flow additive.

Produced by flame hydrolysis of volatile silicon compounds, Fumed Silica, also known as amorphous silica, pyrogenic silica and silicon dioxide, is used as an additive in coatings, liquids, powders and solids.

Fumed Silica with its ability to increase viscosity, is widely used as a thickening agent. It is often used as an anti-caking agent; the sub-micron that moves between the larger particles, creating a surface layer that acts as a lubricant. Fumed Silica’s physical characteristics make it a popular choice for cosmetic applications, offering gentle abrasion or light diffusion properties.

These are some of the different applications where Fumed Silica is used:

  • Adhesives
  • Composites
  • Defoamers
  • Liquid Silicone Rubber
  • Pharmaceuticals
  • Printing Inks
  • RTV Silicone Sealant
  • Thermal / Vacuum insulation material
  • Batteries
  • Cosmetics
  • HTV Silicone Rubber
  • Liquid Silicone Rubber
  • Paints & Coatings
  • Pigments
  • PVC
  • Sealants
  • Unsaturated polyester resins
