Zinc Stearate

Item No: Pzs 202

Zinc stearate is insoluble in polar solvents but soluble in aromatic compounds and chlorinated hydrocarbons when heated, making it suitable for use as a release agent and lubricant in the plastics and rubber industries. Additionally, it serves as an acid breaker and process aid in certain polyolefins.

Zinc stearate is used in the paint and coating industry to suspend pigments, improve grinding, and enhance opacity. In construction, zinc stearate is used as a hydrophobic agent for gypsum. It provides properties like smooth surface, low friction, high resolution, and thermal stability, making it suitable for various transparent polymers and impact-resistant grades.


·         Plastics and Rubber Industry: Zinc stearate improves processing efficiency, prevents adhesion, and enhances mold release in plastics and rubber production.

·         Paint and Coatings Industry: Zinc stearate enhances flow, leveling, and anti-settling properties as a flatting agent and viscosity modifier in paints, coatings, and varnishes.

·         Cosmetics and Personal Care Products: Zinc stearate enhances texture, stability, and prevents caking as a binder, emulsion stabilizer, and anti-caking agent in cosmetic formulations.

·         Pharmaceutical Industry: Zinc stearate aids in easy tablet release, prevents adhesion, and acts as a lubricant and glidant in tablet manufacturing.

·         Textile Industry: Zinc stearate improves fiber processing and reduces static electricity as a lubricant and anti-static agent in the textile industry.

In the Pishrochem, zinc stearate is produced from the reaction of stearic acid and zinc salt. The application of zinc stearate in the rubber industry is the masterbatch color of volcanic powders.
