Uses:
Mainly used in the production of stearate: sodium stearate calcium stearate stearic acid magnesium stearate Lead stearate aluminum stearate potassium stearate iron cadmium stearate widely used in cosmetics, plastic cold plasticizers, release agents, stabilizers, surfactants, rubber vulcanization accelerator, waterproof agent, polishing agent, metal soap, metal mineral flotation agents, softeners, pharmaceuticals and other organic chemicals.
In addition, it can be used as a solvent of oil-soluble pigments , lubricant transfer of crayons, lighting agent of waxed paper, emulsifier of Glycerol Stearate.
•Plastics industry
Stearic acid is widely used in PVC plastic pipe, sheet, profiles, film manufacturing. PVC heat stabilizer has very good lubrication and good light, heat stability.
•Rubber Industry
Stearic acid in rubber synthesis and processing play an important role in the process. Stearic acid is widely used as the vulcanization active agent in natural rubber, synthetic rubber and latex, or as plasticizer and softener.
•Cosmetic industry
Stearic acid used in skin care products such as vanishing cream and cold cream, acting as emulsifier to make them into a white paste. It also can be used in soap products
