Product Description:
Zinc stearate is a white, fine - powdered substance with a faint, characteristic smell. It is insoluble in water but shows solubility in organic solvents like ethanol and benzene. With a relatively high melting point, it remains stable under common processing conditions. In the plastics industry, it serves as a multifunctional additive. As a lubricant, it reduces friction during plastic processing, such as in injection - molding and extrusion, ensuring smooth material flow and preventing sticking to molds. It also acts as a stabilizer, protecting plastics from heat - induced degradation and enhancing their long - term durability. In the rubber industry, it functions as a vulcanization activator and a release agent. It speeds up the vulcanization process, improving the strength and elasticity of rubber products, and helps in easy separation of rubber from molds. In the paint and coatings industry, zinc stearate is used to improve the anti - settling property of pigments, ensuring uniform distribution and enhancing the gloss and smoothness of the final coating. In the cosmetics industry, it can be found in products like powders and creams, where it contributes to a silky texture and better adhesion. However, when handling zinc stearate, it is crucial to avoid inhaling the powder, as it may cause respiratory discomfort. Storage in a cool, dry environment away from heat sources and oxidizing agents is recommended to maintain its quality.

 

Application: 

Zinc stearate has wide applications. In plastics, it works as a lubricant for smooth processing and a stabilizer against heat degradation. In rubber, it acts as a vulcanization activator and release agent. In paint, it improves pigment anti - settling, enhancing gloss and smoothness. In cosmetics, it provides a silky feel and better adhesion in powders and creams. Caution should be taken when handling it to avoid inhaling the powder, and it should be stored cool and dry.
