calcium zinc stabilizer for pvc
Calcium zinc stabilizers for PVC represent a significant advancement in eco-friendly stabilization technology, serving as a crucial additive in PVC processing. These stabilizers effectively prevent PVC degradation during processing and extend the material's service life. The stabilizer system combines calcium and zinc compounds in optimized ratios, providing excellent heat stability and color hold during PVC processing. As a non-toxic alternative to traditional lead-based stabilizers, calcium zinc stabilizers have gained widespread acceptance in various industries. They demonstrate remarkable effectiveness in maintaining PVC's structural integrity while processing at high temperatures, preventing discoloration, and ensuring consistent product quality. The stabilizer system works by neutralizing hydrogen chloride released during processing, while simultaneously preventing auto-catalytic degradation of the PVC polymer chain. Their technical features include superior initial color, excellent transparency in final products, and outstanding long-term stability. These stabilizers find extensive applications in rigid PVC products, including window profiles, pipes, fittings, sheets, and medical devices. The calcium zinc system also provides excellent weather resistance, making it ideal for outdoor applications. In modern PVC processing, these stabilizers have become indispensable due to their balanced performance characteristics and environmental compliance.
