Application

1)In rubber industry: Stearic acid is used as vulcanization activator of rubber ploymer and latex, also softener.

2) In plastics industry: Stearic acid is widely used in pipes, board, profile and film as plasticizer, stabilizer, lube lubricant.

3)In textile industry: Yarn lubricant.

4).In curing agent, plastic heat stabilizer, wetting agent, textile softener, chemical fiber oil, anti-static agent, edible emulsifier

5)In cosmetics, detergent and the intermediates of various surfactants, etc.

6).In other way. Stearic acid is also used to make release agent, calcium steatate, anti-foam additive, Drug-free, Environment-friendly materials.
