Precipitated & Fumed Silica

Amorphous precipitated and fumed silica are manufactured synthetic SiO2 products via precipitation methods and flame-based processes.

These products serve industries in mechanical rubber goods, shoe soles, tire, silicone rubber, animal feed, paints, coatings & inks, oral care, adhesives, detergents, refractory, civil engineering, paper and cardboard, ceramic and general chemicals.

Precipitated Silica

  • Surface area range: 60-200 m2/g
  • Particle size: average 120 microns, milled fine powder 5- 20 microns
  • Pore diameter: >300A
  • Forms: powder (conventional), granular (environmental friendly), high dispersible free-flowing powder, and high dispersible micro pearl (HD)
  • Packaging: 20kg, 25kg, 400kg polypropylene bags and low melt plastic bags

Fumed Silica

  • Surface area range: 150-400 m2/g
  • Particle size: < 15 microns
  • Pore diameter: non-porous
  • Packaging: 10kg paper bags

RS-Sil is a series of untreated, high-purity amorphous fumed silica.

RS-Sil T grades are hydrophobic fumed silica post surface treated with dichlordimethylsilane (DDS).

RS-Sil S grades are hydrophobic fumed silica post surface treated with hexamethyldisilazane (HMDS).

Applications
Carrier and free-flowing/anti-caking agent
Used as anti-caking agents processing aids, and dispersants in foods, feeds and chemicals. All of our products comply with all criteria established by FAMI-QS and the Food and Drug Administration (FDA) application percentages.
Reinforcing filler
Used in rubber industry, including tire tread, general rubber goods, light colored and translucent soles, and OTR tire tread.
Dental abrasive and thickening agent
Designed to act as abrasive and thickening agent in toothpaste formulations.
Matting and thickening agent

Reduces gloss in coatings when solvents evaporate reducing the film thickness. This allows particles to form a micro rug on the surface of the dried film to disperse reflected light rays.

Insulation material

Used in cable insulation, thermal insulation, and vacuum insulation panels due to its low thermal and electrical conductivity.
