Foamed PVC stabilizers are essential additives used in the production of PVC sheets and profiles, ensuring protection against thermal degradation and maintaining color stability throughout processing. Lead-based stabilizers have long been applied due to their strong thermal stability and cost efficiency, but environmental concerns have reduced their use in many applications. As a modern alternative, Calcium-Zinc stabilizers offer a lead-free, eco-friendly solution that improves whiteness retention, enhances color consistency, and provides stable conditions for producing high-quality foamed PVC. These advantages make Ca-Zn systems a reliable and sustainable choice for the future of foamed PVC production
