Zinc Stearate Precipitated is a fine, white powder widely used as a processing aid in the PVC and rubber industries. It is a metallic soap of stearic acid, characterized by its hydrophobic nature, low melting point, and excellent lubricating properties. In PVC processing, it functions primarily as an internal and external lubricant, improving melt flow and reducing friction during extrusion and molding operations.
In rubber compounding, Zinc Stearate is used as a mold release agent and processing aid, facilitating smoother demolding and improved surface finish of finished goods. Its fine particle size and consistent dispersion support uniform mixing and stable processing conditions. The precipitated grade offers controlled particle size and better performance consistency compared to fused grades.
This product is suitable for use in standard industrial formulations where lubrication, release properties, and ease of processing are required.
