Non-Toxic Calcium Zinc Stabilizers from China Suppliers - Eco-Friendly PVC Factory 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 property contributes 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.
Advantage of our Calcium Zinc Stabilizer
- Non-toxic & environmental-friendly, no harmful heavy metal
- Improve the melt fluidity, better dispersity, improve surface gloss quality, reduce mechanical wear
- Anti-precipitation, can improve the extrusion speed, reduce the plasticizing temperature, prolong the production cycle
- Balance of lubrication, promote fusion & improve mechanical property of PVC products
- Cost-effective solution, can replace the traditional lead salt heat stabilizer
- Powder form is conducive for processing and can replace the traditional lead salt heat stabilizer
- Good forming stability

Frequently Asked Questions (FAQ)
Calcium zinc stabilizers offer outstanding thermal stability, transparency, and initial tinting strength. They protect PVC products from degradation at high processing temperatures without causing surface precipitation or migration.
Yes. Due to their excellent light stability, these stabilizers provide superior weather resistance, protecting PVC products from UV radiation, moisture, and color fading in outdoor applications.
Yes, our Calcium Zinc Stabilizers are completely non-toxic and environmental-friendly, containing no harmful heavy metals, making them a sustainable alternative to traditional lead salt stabilizers.
They enhance melt fluidity and dispersity, prevent precipitation, lower plasticizing temperatures, and increase extrusion speeds. This reduces mechanical wear and extends the overall production cycle.
Recommended dosages are 2.5-4.0 PHR for PVC water inlet pipes, 3.0-4.0 PHR for PVC conduit pipes, and 4.0-6.0 PHR for PVC foam sheets to ensure optimal performance.
