Non-Toxic Calcium Zinc Stabilizers from China Suppliers & Factory for Enhanced PVC Safety and Performance
Properties of Calcium Zinc Stabilizer
1. Excellent Thermal stability and Initial tinting
Calcium zinc stabilizers exhibit decent thermal stability, transparency and tinting strength, allowing them to withstand high processing temperatures without surface precipitation and migration, ensuring the PVC products with heat-resistance. These properties contribute to improve long-term performance of PVC products under high-temperature conditions, making them a sustainable choice for stabilizing PVC formulations.
2. Weather-resistance
The good light stability enabled Calcium zinc stabilizers provide excellent weather resistance to PVC products, protecting them from degradation caused by exposure to UV radiation, moisture, and other environmental factors. This property is particularly beneficial for outdoor applications, where durability and colour retention are essential.
Advantage of our Calcium Zinc Stabilizer
1. Non-toxic & environmental-friendly, no harmful heavy metal
2. Improve the melt fluidity, better dispersity, improve surface gloss quality, reduce mechanical wear
3. Anti-precipitation, can improve the extrusion speed, reduce the plasticizing temperature, prolong the production cycle
