Calcium Zinc Stabilizer
Calcium Zinc Stabilizer is a heavy-metal-free PVC heat stabilizer system combining calcium and zinc salts with co-stabilizers and lubricants, offering an environmentally safe alternative to lead and cadmium-based systems. It provides excellent long-term thermal stability and good initial coloring performance for rigid and flexible PVC formulations. Ca-Zn stabilizers are widely used in food-contact, medical, and children's product applications.
