Lithium grease is a multipurpose lubricant that consists of a lithium soap thickener and mineral oil or synthetic base oil. It is known for its excellent resistance to water, heat, and oxidation, making it suitable for a wide range of industrial and automotive applications. However, when it comes to using lithium grease on rubber, caution must be exercised.
Certain types of rubber, such as nitrile rubber (NBR) and fluoroelastomers (FKM), are generally compatible with lithium grease. These rubber materials are commonly used in seals, O-rings, and other components that require lubrication. Lithium grease can help reduce friction, prevent wear, and extend the life of these rubber parts.
On the other hand, some rubber materials, particularly those with high oil resistance, may not be suitable for use with lithium grease. For example, silicone rubber and ethylene propylene diene monomer (EPDM) rubber can swell or degrade when exposed to mineral oil-based lubricants like lithium grease. In these cases, it is essential to select a lubricant specifically formulated for compatibility with the rubber material.
