Applications:
High Lubricity Calcium Zinc Stabilizer is an eco-friendly and high-efficiency thermal auxiliary specially developed for PVC foam extrusion production, perfectly applicable to foam profiles, plates and pipes manufacturing. Adopting advanced compound formula, this product integrates excellent internal and external lubrication performance with outstanding thermal stability, fully meeting the technical requirements of PVC foam extrusion molding.
During high-temperature extrusion processing, PVC materials are prone to thermal aging, molecular chain fracture and surface yellowing. This calcium zinc stabilizer can effectively restrain thermal decomposition, maintain stable melt state, and avoid deformation, bubbling and poor surface finish of foam products. Its superior lubricating property optimizes melt fluidity, reduces machine running resistance, lowers equipment wear and energy consumption, and greatly improves production efficiency and product yield.
The product features good compatibility with PVC resin, calcium powder and other additives, uniform dispersion without precipitation. It helps foam products form fine and even cell structure, stable density and solid overall performance. Free of heavy metal ingredients, it conforms to environmental protection regulations, suitable for indoor and outdoor PVC foam profiles, sheets and pipes. With small addition amount, stable processing performance and long service life of finished goods, it becomes an ideal formula raw material for PVC foam extrusion manufacturers.
