Lithium soap

Lithium soaps are used as lubricant components and form-release agents at relatively high temperatures.

[4] Lubricating greases are commonly formulated as mixtures of an oil and a lithium soap thickener.

[5] Some formulations include PTFE or other substances, such as molybdenum disulfide.

Lithium grease adheres particularly well to metal, is non-corrosive, may be used under heavy loads, and exhibits good temperature tolerance.

It has a dropping point of 190 to 220 °C (370 to 430 °F) and resists moisture, so it is commonly used as lubricant in household products, such as electric garage doors, as well as in automotive applications, such as constant-velocity joints.
