it is understood that: barium stearate, white or slightly yellow amorphous powder, melting point >225℃, has a stimulating effect on the central nervous system, soluble in hot ethanol, benzene, toluene and other non-polar solvents are insoluble in water and ethanol. it is heated and dissolved in an organic solvent and becomes a gel when cooled, and is water-absorbent in the air. no sulfide contamination. when encountering strong acid, it decomposes into stearic acid and the corresponding barium salt.
barium stearate can be used as the following additives:
1. used as a high-temperature resistant lubricant for machines and a high-temperature resistant additive for rubber products. agent, light-resistant and heat-resistant stabilizer for pvc plastics.
2. used as a heat stabilizer for polyvinyl chloride products.
3. used as waterproofing agent, lubricant and bearing lining material;
4. used as high-temperature resistant powder for rubber products. it can be used as a stabilizer and lubricant for polyvinyl chloride. among all stearic acid lubricants and alkaline earth metals, this product has the best long-term heat resistance. mainly used for soft transparent films, sheets, artificial leather, stearic boards, tubes, etc. it can also be used as a high-temperature release agent and a high-temperature lubricant for machinery.
