The Ca-Zn stabilizer is a cutting-edge, eco-friendly solution designed to deliver exceptional thermal stability in PVC processing. As a leading alternative to traditional heavy metal-based stabilizers, the Ca-Zn stabilizer excels in high-temperature environments (160–220°C), ensuring optimal performance while adhering to global environmental standards.

A key strength of the Ca-Zn stabilizer lies in its ability to effectively suppress PVC degradation. During processing, PVC releases corrosive hydrogen chloride (HCl), which accelerates chain scission and discoloration. The Ca-Zn stabilizer neutralizes HCl through synergistic reactions between calcium and zinc compounds, significantly delaying decomposition and maintaining the material’s structural integrity and visual clarity. This mechanism makes the Ca-Zn stabilizer ideal for applications requiring long-term thermal resistance, such as construction profiles, pipes, and transparent films.

Furthermore, the Ca-Zn stabilizer achieves enhanced stability via synergistic effects with co-stabilizers like polyols and β-diketones. These additives work collaboratively with the Ca-Zn stabilizer to scavenge free radicals, stabilize unstable chlorides, and improve overall heat resistance. This multi-component interaction ensures prolonged thermal protection, even under continuous thermal stress, making the Ca-Zn stabilizer suitable for demanding applications like automotive cables and outdoor

In addition to thermal performance, the Ca-Zn stabilizer offers excellent compatibility with PVC resins and auxiliary additives, enabling flexible formulation designs. Its lubricating properties reduce processing friction, extending equipment lifespan while maintaining smooth production workflows.

Environmentally, the Ca-Zn stabilizer stands out as a non-toxic, heavy metal-free solution, fully compliant with RoHS, REACH, and food-contact regulations. It is widely used in sensitive sectors, including food packaging, medical devices, and children’s toys.

In summary, the Ca-Zn stabilizer combines superior thermal stability, eco-safety, and versatility, making it the go-to choice for sustainable PVC manufacturing. By integrating advanced stabilization technologies, the Ca-Zn stabilizer continues to redefine industry standards for performance and environmental responsibility.
