Purpose

Used as a heat stabilizer for polyvinyl chloride and lubricant for various plastic processing, release agent, etc. In hard products, the gel speed can be improved by combining with basic lead salt and lead soap. It is also used for food packaging, medical equipment, and other non-toxic soft films and appliances. It can also be used as a halogen absorber for polyethylene and polypropylene to eliminate the adverse effects of residual catalysts on color and stability. As a plasticizer in rubber processing, it can soften natural rubber and complete rubber, with almost no effect on vulcanization. It is also used as a lubricant for polyolefin fibers and molded plastics, a thickener for lubricating grease, a waterproof agent for textiles, a leveling agent for paints, and a plasticizer for making plastic records. Used as halogen absorbents in polyethylene and polypropylene; Lubricants and release agents for thermosetting plastics such as phenolic and amino acids; Thickening agent for lubricating grease; Waterproofing agent for waterproof fabrics; Paint smoothing agent and pencil lead lubricant, etc. Food grade calcium stearate is used as an anticancer agent. Calcium stearate is also used in pencil lead production and in the pharmaceutical and spice industries.
