Calcium Greases
Calcium greases are smooth and buttery in texture, have excellent water resistance, a fair mechanical stability, are easy to apply and have melting points just under the boiling point of water. Their lower temperature characteristics are governed by the mineral oil. Their maximum temperature is usually limited to about 65°C, while they may survive 95°C for short periods of time. Applications are found in the automotive and farm industries. Other uses include chassis lube, mine car grease, fifth wheel grease, track roll grease and water pump grease.
Calcium 12 Hydroxy Stearate grease
This grease is made by reacting 12-hydroxy-stearic acid with hydrated lime and diluting with mineral oil. It is sometimes referred to as anhydrous calcium grease. It has excellent water resistance, good mechanical stability, and its low temperature properties are also dependent on the mineral oil used. The melting or dropping point is usually around 120°C and can be used in areas where conventional calcium can not.
