Purpose Editing Broadcast

Mainly used for the production of stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, and potassium stearate.

Widely used in cosmetics, plastic cold resistant plasticizers, release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals, and other organic chemicals.

In addition, it can also be used as a solvent for oil-soluble pigments, a wax pencil smoothing agent, a wax paper polishing agent, and an emulsifier for stearic acid glyceride.

This product is used as a lubricant, defoamer, and food additive in the food industry as raw materials for stearic acid glyceride, stearic acid sorbitol anhydride ester, sucrose ester, etc. Raw materials used as additives and for daily chemical products.

Stearic acid is widely used in the manufacturing of PVC plastic pipes, plates, profiles, and films. It is a PVC heat stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps to prevent “coking” during the processing. Adding it to PVC film processing is an effective heat stabilizer and can also prevent 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 agent in natural rubber, synthetic rubber, and latex, and can also be used as a plasticizer and softener. Stearic acid needs to be added as an emulsifier in the production of synthetic rubber. When making foam rubber, stearic acid can be used as a foaming agent, and stearic acid can also be used as a release agent for rubber products.

Cosmetics industry

Stearic acid is used in skincare products such as snow cream and cold cream to emulsify and turn it into a stable and white cream. Stearic acid is also the main raw material for making almond honey and milk. Stearic acid soap esters are more widely used in the cosmetics industry.
