CHNV ZINC STEARATE is a high-purity metallic stearate compound widely used as an internal and external lubricant, release agent, and processing aid in thermoplastic and rubber manufacturing. It improves flow characteristics, reduces friction during molding and extrusion, and enhances surface finish. This grade is particularly suited for PVC, polyolefins, and elastomers where consistent performance and low contamination are critical.
