Applications: Calcium stearate is used as a non-toxic heat stabilizer for polyvinyl chloride, offering good lubricity, non-toxicity, and excellent processing performance. It is commonly used in food packaging films, medical devices, and other non-toxic soft products. When used together with basic lead salts and lead soaps in rigid products, it can enhance the gelation speed. In polyethylene and polypropylene, it eliminates the adverse effects of residual catalysts on resin color and stability. It is also widely used as a lubricant and release agent for thermosetting plastics such as polyolefins, polyester reinforced plastics, phenolic resins, and amino resins.
Packaging and Storage: This product is packaged in 20 kg bags per bag, with woven bags and inner liners. Store in a cool, ventilated, and dry place. Keep away from fire and moisture. Do not store together with acids, alkalis, or corrosive substances.
