Zinc Stearate is a crucial chemical auxiliary agent widely recognized for its versatility and effectiveness across numerous industrial applications. This fine white powder, with the CAS number 557-05-1, is an organic compound presenting as the zinc salt of stearic acid.

Known for its insolubility in water, Zinc Stearate serves multiple vital functions. One of its primary roles is as an exceptional release agent, particularly beneficial in the production of Sheet Molding Compound (SMC) and various other molding processes. Its lubricating properties ensure smooth demolding, enhancing production efficiency and the quality of finished goods.

Furthermore, Industrial Grade Zinc Stearate acts as an effective heat stabilizer, especially in materials like Polyvinyl Chloride (PVC) and Acrylonitrile Butadiene Styrene (ABS). It helps to prevent degradation caused by heat during processing, extending the lifespan and maintaining the structural integrity and color of the final plastic products.

Beyond its roles as a release agent and heat stabilizer, Zinc Stearate functions as a valuable lubricant in a range of polymer systems, including styrene resin, phenolic resin, amine resin, polyethylene, and other synthetic resins. In the rubber industry, it serves as both a vulcanizing active agent and a softener, improving processability and performance.

Additional applications include its use as a waterproofing powder in building materials, where it repels moisture effectively. It is also utilized as a paint polish and polish oil extender, contributing to smoother finishes and enhanced dispersion.

Characterized by its consistent quality, typical specifications for industrial grade Zinc Stearate include a zinc content (Zn) of 10.3-11.3%, maximum free acid (as stearic acid) of 0.8%, maximum moisture content of 1.0%, and a minimum size passing through 200 Mesh of 99.0%. This adherence to strict purity standards ensures reliable performance in demanding industrial environments.

Supplied typically in 25kg bags, this indispensable auxiliary agent is a cornerstone for manufacturers aiming for high-quality outputs in plastics, rubber, coatings, and construction materials. For those requiring this essential ingredient, samples are often available for testing to ensure compatibility with specific formulations and processes.

Procuring high-quality Zinc Stearate powder is essential for consistent manufacturing. As a reliable Zinc Stearate manufacturer and supplier, detailed information regarding the current Zinc Stearate price, as well as guidance on how to effectively buy or purchase this industrial grade chemical auxiliary, is readily available to meet diverse industrial needs.
