Zinc stearate : Zn-St (C36H70O4Zn)
Zinc stearate (C₃₆H₇₀O₄Zn) is a fine white powder that is insoluble in water and widely used as a high-performance processing additive in various industrial applications. It is the zinc salt of stearic acid, providing excellent lubrication, mold release, and heat stabilization properties in plastic and rubber formulations. As a non-lead and heavy-metal-free stabilizer, zinc stearate serves as a safer alternative to traditional lead-based additives, supporting environmentally friendly and regulatory-compliant manufacturing processes.
With more than 30 years of experience in chemical supplier and manufacturing industry, Evergreen Chemical Company Thailand is known for reliable and consistent product quality backed by strict testing protocols across Asia and beyond.
