Calcium Stearate : Ca-St (C36H70CaO4)
Calcium stearate (C₃₆H₇₀CaO₄) is a fine white powder that is insoluble in water and widely used as a multifunctional additive in various industrial applications. It is the calcium salt of stearic acid, providing effective lubrication and heat stabilization properties in plastic and PVC formulations. As a non-lead stabilizer, calcium stearate offers a safer, heavy-metal-free alternative to traditional lead-based additives, supporting environmentally friendly and regulatory-compliant production processes.
