Application
Zinc Stearate serves as a heat stabilizer, lubricant, grease, accelerator, and thickener. Widely used as a PVC resin heat stabilizer, it is suitable for industrial transparent products and, when combined with calcium soap, non-toxic applications.
While traditionally used in soft products, it now also enhances rigid transparent items like water bottles and pipes, improving lubricity and reducing scaling. Additionally, it functions as a release agent, paint matting agent, and coating additive.
