A non-liquid, semi-solid lubricant. Often a soap, emulsified with mineral or vegetable oil. High thixotropic effect is typically required. Greases are used where a mechanism can only be lubricated infrequently and where a lubricating oil would not stay in position.
AEROSIL® fumed silica can be used as an additive in soap greases for further improvement of the grease quality. In some applications, a small amount of hydrophilic fumed silica (e.g. AEROSIL® 200) can be helpful to absorb water or oil. Hydrophobic fumed silica types (e.g. AEROSIL® R 202 or R 805) can help to improve water resistance or anti corrosion properties of soap greases.
