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
