AEROSIL® fumed silica for non-soap greases

AEROSIL® fumed silica is used as a thickener in non-soap greases. Besides the thickening effect, AEROSIL® fumed silica can also have an influence on many other properties.



Often specialty grease, thickened by inorganic thickeners (AEROSIL® fumed silica). High thixotropic effect is typically required. Non-Soap greases are used in high-temp. applications as well as for multi-purpose greases.  

Benefits of AEROSIL® fumed silica as thickener in non-soap greases:
  • Rheological properties (e.g. viscosity, yield point, structure stability, thick recovery)

  • Modify friction (improve energy efficiency – at higher shear – not boundary lubrication)

  • • Mechanical stability (e.g. stability at high shear)

  • • Oil separation characteristic / oil keeping ability

  • • Higher temperature range / Raises dropping point performance

  • Environmentally safe / low-emission

  • Prevent settling / the formation of sludge (dispersants)

  • Color → White/Translucent

  • High chemical purity

  • Oxidation stability (Restrain oxidation; reduce rusting)

  • Improvement of water and acid resistance
