Non-Toxic Calcium Zinc Stabilizers from China Suppliers - Eco-Friendly PVC Solutions from Our Factory
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
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
4. Balance of lubrication, promote fusion & improve mechanical property of PVC products
5. Cost-effective solution, can replace the traditional lead salt heat stabilizer
6. Powder form is conducive for processing and can replace the traditional lead salt heat stabilizer
7. Good forming stability

Frequently Asked Questions
Q1: What are the primary properties of your Calcium Zinc Stabilizers?
Our Calcium Zinc Stabilizers feature excellent thermal stability, great initial tinting strength, transparency, and outstanding weather-resistance. They protect PVC products from degradation caused by UV radiation, moisture, and high temperatures.
Q2: Are Calcium Zinc Stabilizers environmentally friendly?
Yes, they are non-toxic, eco-friendly, and contain no harmful heavy metals. They serve as a safe and sustainable replacement for traditional lead salt heat stabilizers.
Q3: How do these stabilizers improve the PVC manufacturing process?
They help improve melt fluidity and dispersity, reduce mechanical wear, prevent precipitation, and allow for higher extrusion speeds while reducing the plasticizing temperature, which ultimately prolongs the production cycle.
Q4: What is the recommended dosage for PVC conduit pipes and foam sheets?
The recommended dosage is 3.0 to 4.0 PHR for PVC conduit pipes, and 4.0 to 6.0 PHR for PVC foam sheets, depending on your processing conditions.
Q5: Can these stabilizers be used in outdoor PVC applications?
Yes. Thanks to their superior weather-resistance and light stability, they protect PVC products from degradation caused by UV rays and moisture, making them ideal for outdoor applications like WPC foam boards and pipes.
