Stearic acid salt:
Can be used as a heat stabilizer for PVC, increasing transparency and semi transparency, softener, lubricant, and film-forming agent. Can react with hydrochloric acid produced by the thermal decomposition of PVC to prevent decomposition; At the same time, it is also a good light stabilizer that can inhibit the aging of the film by ultraviolet rays and extend its lifespan.

In the paint industry, it can be used as a drying agent to shorten the drying time, and also as a leveling agent. In polymer materials, it is used as a release agent, activator, stabilizer, lubricant, softener, etc. In the mechanical industry, it can be used as a high-temperature solid lubricant. High temperature resistant powder molding agent for rubber products. Thickening agents for lubricating oil and adhesives, temperature resistant agents for lubricating grease, and waterproofing agents for paper, coatings, waterproofing, and rainproof materials. Pencil lead lubricant, powder mold for pharmaceuticals. Thickening agents and lubricants in the cosmetics industry can also be used as waterproofing agents for fabrics and building materials.
