Ca Zn composite stabilizer is specially developed for PVC processing and formulated with modified organic calcium-zinc systems. The product has passed SGS testing with no heavy metal precipitation. During high-temperature processing, it can long-term inhibit PVC decomposition, significantly improve initial color retention and long-term thermal stability, and eliminate blooming and precipitation defects on product surfaces. Equipped with a balanced internal and external lubrication system, it is compatible with extrusion, calendering, injection molding and other processes. It is widely used in high-safety products including children’s plastic articles, food packaging and medical flexible hoses.

Product Advantages

Non-toxic, eco-friendly and safe

Free of harmful heavy metals such as lead and cadmium, and free of sulfide contamination. It meets strict compliance standards for food-contact materials, maternal and infant products, export goods and other applications.

Outstanding thermal stability

Delivers excellent thermal performance with balanced early-stage color inhibition and long-term aging resistance. It effectively reduces yellowing and cracking of finished products, and features remarkable weather resistance and anti-precipitation properties.

Superior processability

Featuring a well-balanced formula with built-in internal and external lubrication systems, it offers favorable melt fluidity and a wide processing window. Compatible with extrusion, injection molding, calendering and other processes, it resists scaling and precipitation during continuous production, greatly cutting equipment cleaning costs and boosting production efficiency.

Applications

Ca Zn stabilizer boasts a wide range of application scenarios covering all types of PVC and polymer products. For rigid products, it is applicable to construction materials including PVC door and window profiles, pipes and fittings, decorative boards, SPC flooring, etc. For flexible products, it suits wire and cable sheaths, plastic films, flexible hoses, sealing strips, artificial leather and other goods. In addition, it can be used in high-end eco-friendly fields such as food packaging films, medical plastic accessories and children’s plastic products. It is also fit for mass production of various daily-use and industrial plastic products with strong general versatility.
