Application

Stearic acid is mainly used in the production of stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate,  iron stearate, potassium stearate.
Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films. It is PVC heat stabilizer with good lubricity and better light and heat stabilization. In plastic PVC pipes, stearic acid helps to prevent "coking" during processing. It is an effective heat stabilizer when added to PVC film processing, and can also defend against discoloration of the finished film caused by exposure to sulfides.
Rubber industry
Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanizing active agent in natural rubber, synthetic rubber and latex, and can also be used as a plasticizer and softener. In the production of synthetic rubber, stearic acid is added as emulsifier, in the manufacture of foam rubber, stearic acid can be used as a foaming agent, stearic acid can also be used as a mold release agent for rubber products.
Cosmetic Industry
Stearic acid is used as emulsifier in two types of skin care products, namely, snow cream and cold cream, so as to make it into a stable and white paste. Stearic acid is also a major ingredient in the manufacture of almond nectar and milk. Stearic acid saponates are more widely used in the cosmetic industry.
