stearic acid

详情

1.Description:

 It is an important chemical raw material and additive, widely used in rubber, plastics, cosmetics, pharmaceuticals, chemical auxiliary agent industries etc. Stearic acid, also called octadecanoic acid, is one of the useful types of saturated fatty acids that comes from many animal and vegetable fats and oils. Stearic acid is useful as an ingredient in making candles, soaps, and cosmetics and for softening rubber.
 

2. Usage:

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, and lube lubricant.

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