Why Are Ca-Zn Stabilizers Replacing Lead-Based Stabilizers?

Lead-based stabilizers were used in PVC stabilization for many years. However, due to increasing regulations, impacts on human health and sustainability requirements, Ca-Zn stabilizers have become the global standard.

1. Regulatory Priority

• Lead is toxic and banned in the EU.

• RoHS and REACH are incompatible.

• Ca-Zn → 100% environmentally friendly and compatible.

2. Performance Advantages

• Less color change

• Cleaner process

• Lower odor and more stable heat resistance

• Provides high transparency

3. Cost and Compatibility

Although Ca-Zn systems may seem costly in the initial investment, in the long run:

• lower waste

• better process stability

• ensures export compliance

.

Conclusion

Ca-Zn is a modern, safe and globally accepted stabilization system that replaces lead-based stabilizers.
