TAMMECH R-551
TAMMECH R-551, a Lithium Hydroxide Monohydrate (56.5% min), is a lithium soap used widely in lubricating greases. Lithium soaps deliver high oxidation stability and dropping points up to ~200 °C. R-551 is a free-flowing white fine powder with greatly reduced levels of CaO, NaOH, and Mg; the purified grade is used in specialty grease manufacture.
Features
- Provides excellent resistance to water.
- Improves grease dropping point.
- Enhances oxidative, mechanical, and thermal stability of grease.
Applications
- Used in manufacturing of greases and other specialty chemicals.
TAMMECH R-552
TAMMECH R-552 is 12-hydroxystearic acid (12-HSA), the mixed fatty acid obtained by hydrolysis of hydrogenated castor oil. Used in grease manufacturing, it is a high-melting, brittle, waxy solid at ambient temperatures. The 12-HSA content in hydrogenated castor-oil fatty acids is about 83–90%.
Features
- Provides excellent resistance to water.
- Improves grease dropping point.
- Good oxidative and mechanical stability.
Applications
- Used in manufacturing of greases and lubricants.
TAMMECH R-553
TAMMECH R-553 is hydrogenated castor oil (HCO), a wax-like compound obtained by the controlled hydrogenation of refined castor oil. It is a hard, brittle, high melting-point product that is practically odorless and tasteless, supplied as flakes or powder. Chemically, R-553 HCO is the triglyceride primarily of 12-hydroxystearic acid (12-HSA). It is insoluble in water with limited solubility in most organic solvents.
Features
- Hard wax at room temperature with high melting point (85–88 °C).
- Unique particle size distribution.
- Good surface-wetting capabilities.
Applications
- Used in manufacturing of greases and lubricants.
