White or slightly yellow powder, stimulates the central nervous system, soluble in hot ethanol, benzene, toluene and other non-polar solvents, insoluble in water and ethanol.
Molecular formula: C36H70BaO4
White or slightly yellow powder, stimulates the central nervous system, soluble in hot ethanol, benzene, toluene and other non-polar solvents, insoluble in water and ethanol. Gelatinous when heated and dissolved in an organic solvent and cooled; has water absorption in the air. No sulfide pollution. When meet with strong acids, it decomposes into stearic acids and corresponding barium salts.

Used as high-temperature lubricants for machines, high-temperature additives for rubber products, and light-resistant and heat-resistant stabilizers for PVC products; When used as a heat stabilizer for PVC products, it has good long-term heat resistance and lubricity, and the stabilizing effect is bigger than calcium stearate, but less than lead stearate. It has good synergistic effect with cadmium soap, zinc soap or epoxy compound. Used as waterproofing agent, lubricant and bearing liner.
20kg/bag, It should be stored in cool and dry surroundings.
