Zinc Stearate, scientifically known as Zinc distearate or stearic acid zinc salt, with the CAS number 557-05-1, is a chemical compound that plays a significant role across a multitude of industrial applications. As a white, fine powder, it offers a unique combination of properties that make it indispensable in sectors ranging from plastics and rubber to coatings, cosmetics, and pharmaceuticals. Understanding these properties is crucial for procurement professionals and R&D scientists looking to leverage its capabilities. If you are seeking to buy Zinc Stearate, recognizing its characteristics will guide your purchasing decisions.

The physical and chemical properties of Zinc Stearate are key to its widespread use. It is characterized by its excellent lubricity, water repellency, and ability to act as a mold release agent. It is insoluble in water but soluble in hot organic solvents like ethanol and benzene, where it can form gel-like substances upon cooling. Its relative density is approximately 1.095, and it has a melting point typically between 118-125 °C. Notably, it is considered non-toxic and can be safely used in products that come into contact with food, a critical factor for many downstream applications. For companies sourcing this material, a reliable Zinc Stearate supplier is essential.

In the plastics industry, Zinc Stearate serves as a vital lubricant and heat stabilizer for PVC, improving processing efficiency and the quality of finished products. It facilitates better dispersion of pigments and fillers, leading to a more uniform and aesthetically pleasing final product. Similarly, in the rubber industry, it acts as a processing aid and mold release agent, reducing friction and ensuring clean demolding of rubber parts. Manufacturers often inquire about the Zinc Stearate price, balancing its cost against the significant improvements it brings to production.

Beyond polymers, Zinc Stearate finds extensive use in the paints and coatings sector as a matting agent and dispersing aid. Its inclusion helps achieve desired surface finishes and prevents pigment settling. In cosmetics, its smooth texture and anti-caking properties make it ideal for pressed powders and other formulations. For pharmaceuticals, it functions as a tablet lubricant, enhancing manufacturing processes. When you are ready to purchase, considering a reputable Zinc Stearate manufacturer in China can provide access to high-quality materials at competitive prices.
