Type of Base Oil

Mineral Oil

• Lubricating oils are the major components in grease formulations and as such, exert considerable influence on BEHAVIOR of the grease.
• The oxidation resistance of grease may be poor if its base oil component has a low viscosity index or large amounts of sulfur or polynuclear aromatic molecules.

• Synthetic fluids are becoming increasingly important in greases designed for special extreme-temperature applications.
• Synthetic oils have higher viscosities indexes and flashpoints and their pour points are considerably lower.
• This makes them valuable blending components when compounding oils for extreme service at both high and low temperatures.

Type of Thickener

Soap – Thickener Grease 
Grease manufacture varies with the thickener used. Soap thickened greases are like Aluminium Soap Grease, Calcium Soap Grease, Sodium Soap Grease, Lithium Soap Grease, Barium Soap Grease, etc.

Non-Soap Grease
There are, at present, THRE major types of nonsoap greases–organo-clay/bentonite grease, Polyurea Grease, Silica Grease.
