Zinc Stearate (CAS 557-05-1) is a fundamental chemical compound with a broad spectrum of industrial applications, celebrated for its versatility and performance-enhancing properties. As a leading manufacturer and supplier of specialty chemicals in China, we aim to provide in-depth knowledge about this essential additive, empowering businesses to make informed purchasing decisions.

At its core, Zinc Stearate is a metal stearate, essentially a zinc salt of stearic acid. It presents as a white, non-toxic, fine powder that is insoluble in water but soluble in hot organic solvents and acids. This insolubility in water confers its characteristic hydrophobic or water-repellent properties. Its chemical formula, C36H70O4Zn, and molecular weight of approximately 632.33 g/mol are key identifiers for procurement.

The utility of Zinc Stearate spans across several key industries. In the plastics sector, it is extensively employed as an internal lubricant and a mold release agent. Its presence facilitates smoother processing, prevents sticking to machinery, and aids in the easy extraction of molded parts. This directly translates to improved production efficiency and better surface finish for plastic products. For buyers seeking a reliable source, understanding these functions is crucial when you buy Zinc Stearate.

In the rubber industry, Zinc Stearate acts as a softener and an anti-adhesion agent. It improves the malleability of rubber compounds, making them easier to work with during manufacturing. Its anti-sticking properties are vital for preventing unwanted adhesion during processing and in the final product. Additionally, it can function as a vulcanization activator, potentially speeding up the curing process and enhancing the physical properties of the rubber.

Furthermore, Zinc Stearate finds application in coatings as a flatting agent, controlling gloss levels to achieve desired finishes. In cosmetics, it serves as a lubricant and thickening agent, contributing to the texture and application of powders. Its ability to absorb moisture also makes it useful in certain industrial applications.
