Barium-Zinc Stabilizer is a metal soap-based heat stabilizer designed for flexible PVC systems. It offers reliable thermal protection during soft PVC processing and helps maintain clarity, flexibility, and mechanical strength.
Compared to lead or tin systems, Barium-Zinc offers a balanced cost-performance ratio, especially in extrusion and calendaring operations. It is often used together with plasticizers, lubricants, and other additives.
This stabilizer works well in products that require good electrical insulation, smooth surfaces, and non-migration performance.
