Lithium Grease Formulation
Lithium Grease: General Overview, Composition and Formulation
Lithium grease is a widely used multipurpose grease known for balanced mechanical stability, temperature capability and water resistance. Conventional lithium soap is commonly developed from lithium hydroxide and 12-hydroxystearic acid in a selected base oil.
The formulation is adjusted for bearing speed, load, operating temperature, relubrication interval, NLGI grade and required EP performance. Smoothness, colour, pumpability and oil release are also controlled during development.
General Composition of Lithium Grease
- COMPONENT | PURPOSE
Base oil
Mineral or synthetic oil providing the lubricating film and controlling speed-temperature behaviour.
Lithium soap thickener
Provides structure, mechanical stability and useful resistance to heat and water.
Antioxidant
Reduces oxidation of the oil during storage and service.
Rust inhibitor
Protects ferrous surfaces from corrosion.
Antiwear and EP additives
Improve wear control and load carrying for EP grades.
Tackifier or polymer
Adjusts adhesion, texture and mechanical behaviour.
Dye or solid lubricant
Used for coloured or application-specific products.
Final composition depends on the required NLGI grade and performance specification.
Production Process and Lubechem Technical Support
- TYPICAL MANUFACTURING SEQUENCE
1. Charge the initial base-oil portion.
2. Conduct controlled lithium saponification.
3. Remove water and develop the soap at the required temperature.
4. Add finishing oil in planned stages.
5. Cool under controlled mixing to develop texture.
6. Add temperature-sensitive additives and dye.
7. Mill or homogenise the grease.
8. Deaerate, filter where necessary and test.

Lithium Grease: Frequently Asked Questions
- Can different NLGI grades be developed?
Yes. Thickener level, oil balance and processing are adjusted for the required grade.
Can lithium EP2 grease be developed?
Yes, with compatible EP and antiwear additive technology.
Will Lubechem provide complete raw-material quantities?
The agreed consultancy scope can include a complete composition and batch sheet.
Is remote manufacturing support available?
Yes. Laboratory and production batches can be guided through video calls.
Can lithium grease be mixed with another grease?
Compatibility must be tested before changeover because mixing can alter consistency and performance.
