Premium Calcium Zinc Compound Stabilizer for PVC | Kefeng Chemical 2026

What Is Calcium Zinc Compound Stabilizer?

Calcium Zinc Compound Stabilizer is a non-toxic heat stabilizer blend for PVC resin processing. It combines calcium carboxylates, zinc carboxylates, and co-stabilizers (such as hydrotalcite, epoxidized soybean oil) to prevent PVC chain degradation and discoloration during high-temperature manufacturing and long-term end use.

In practice, our R&D team at Kefeng Chemical has tested over 300 formulation variations over 20 years, and we confirm that properly balanced Calcium Zinc Compound Stabilizer can maintain PVC’s mechanical properties and color stability for over 10 years of outdoor use. Industry consensus in 2026 is that this stabilizer is the most cost-effective eco-friendly replacement for lead-based and cadmium-based stabilizers.

Q: Is Calcium Zinc Compound Stabilizer regulated globally?

A: Yes, Calcium Zinc Compound Stabilizer meets all major global regulatory standards, including REACH (EU), RoHS, and FDA food contact requirements. Unlike lead-based stabilizers, it is not banned in any consumer PVC applications as of 2026.

How to Choose The Right Calcium Zinc Compound Stabilizer

Selecting the correct formulation for your production line ensures optimal performance and reduces waste. Follow these practical steps based on our manufacturing experience:

1. Match stabilizer loading to your PVC type: use 1-3 phr (parts per hundred resin) for flexible PVC (cables, films, toys) and 3-6 phr for rigid PVC (pipes, window profiles, injection molded parts)
2. Verify regulatory alignment: confirm certifications for your target market (e.g. FDA for food packaging, CE for construction products in the EU)
3. Test performance in your specific processing conditions: adjust loading by 0.2-0.5 phr if your line runs 10°C higher or lower than standard temperatures
