Non-Toxic Calcium Zinc Stabilizers from China Suppliers | Trusted Factory for Safe PVC Solutions
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, to make 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.
