Industrial Grade Calcium Stearate Heat Stabilizer for PVC Plastic Processing & Profile Production,
,

Calcium Stearate is a widely used metallic soap and heat stabilizer in PVC plastic processing. It works by stabilizing vinyl chloride resin during high-temperature extrusion, injection molding and calendering, helping prevent thermal decomposition and extending processing time. Our industrial-grade calcium stearate is white fine powder with low moisture content, good dispersibility and stable calcium content. It is suitable for PVC pipes, profiles, fittings, soft films and general plastic products. Besides heat stabilization, it also acts as lubricant and anti-blocking agent in plastic formulations. We offer standard export packaging and stable bulk supply for PVC manufacturers, plastic processing factories and additive compounding plants.
