DUPLAST CAZN to replace Lead based Stabilizers for PVC Applications

DUPLAST has developed CAZN stabilizer as a replacement to lead-based stablizers for PVC processing. The combination of metal salts leads to effective stabilization in PVC processing stability and long-term stability.

The CAZN stabilizers have the advantages of good heat stability and initial colouring property. They also have good processing performance and a wide processing range. Calcium Zinc based stabilizers are relatively eco-friendly whereas lead-based stabilizers are harmful to environment.
