Zinc stearate is insoluble in polar solvents but soluble in aromatic compounds and chlorinated hydrocarbons when heated. It has various applications, primarily in the plastics and rubber industries, where it is used as a releasing agent and composite lubricant. Zinc stearate also functions as an acid breaker and process aid in the production of certain polyolefins. In the paint and coating industries, zinc stearate is utilized to suspend pigments, improve grinding and opacity. It is employed in the construction industry as a water-repellent agent for gypsum, offering characteristics such as a smooth surface, low friction, high resolution, and thermal stability. These properties make it suitable for applications involving PS crystal grade impact and other transparent polymers like PE, PS, PA, PVC, SMC, and BMC. Zinc stearate serves as a lubricant for covering papers and sandpaper. It is used as an additive in the food, pharmaceutical, cosmetic, and healthcare industries. Additionally, it is commonly combined with other stearate salts such as calcium stearate and barium stearate as a raw material to enhance the thermal stability of PVC.
