AEROSIL® fumed silica for lubricants and lubricating greases


The use of AEROSIL® fumed silica is mainly recommended for lubricating greases used in industrial applications, automotive, electrical as well as food grade. 


Lubricants and lubricating greases Tabelle
Benefits of AEROSIL® fumed silica:
  • Hydrophilic AEROSIL® fumed silica provides optimized thickening effects in non-polar oils..

  • Hydrophobic AEROSIL® fumed silica provides viscosity control and increased water repellency in semi-polar to polar oils.

The surface area of AEROSIL® fumed silica and the volume fraction in the final mass play a role in the long term storage and heat stability.

AEROSIL® fumed silica can be used in the following systems:
  • In lubricating oilsas an additive for metal working fluids and wire drawing Lubricants.

  • In soap greases, thickened by fatty acid soaps of lithium, calcium, sodium or aluminum, AEROSIL® fumed silica can be used to further improve the performance of the lubricating grease.

  • In non-soap greases, used in high-temperature applications up to 230° C as well as for extreme-pressure and multipurpose greases.
