Calcium Zinc Stabilizer CZ759 for PVC Pipe Profile Non-Foaming Extrusion Lead-Free PVC Stabilizer

Description

Product Overview

CZ759 is a high-performance calcium-zinc composite stabilizer specially designed for PVC no

n-foaming extrusion processes. It is produced using advanced compounding technology, combining calcium salts, zinc salts, lubricants and antioxidants.

The product is a white powder with good dispersibility and no peculiar odor, suitable for stable PVC processing applications.

Product Performance

During PVC processing, CZ759 effectively:

Inhibits thermal degradation of PVC resin
Controls nucleation and melt stability during processing
Prevents uneven foaming, collapse and yellowing
Ensures uniform density and smooth surface of final products

It has excellent compatibility with PVC resin, ensuring stable processing and high-quality finished products.

Product Advantages

1. Environmental Compliance

Lead-free and cadmium-free formulation, compliant with EU REACH, RoHS and other environmental regulations, suitable for export to Europe and America.

2. Excellent Sulfur Resistance

Strong resistance to sulfur contamination, effectively preventing blackening, discoloration and gloss loss in PVC profiles and window applications, ensuring long-term appearance stability.

3. Strong System Compatibility

Can directly replace lead salt stabilizers and organotin stabilizers. No issues such as color difference, precipitation or stickiness during production switching, ensuring smooth transition and stable processing.

4. Processing and Appearance Performance

Improves plasticization and melt flow stability, reduces torque and energy consumption, increases extrusion efficiency, and improves whiteness, gloss and surface flatness of final products.

5. High Cost Performance

Balanced lubrication system reduces equipment wear, extends screw and mold life, improves production stability, reduces downtime, and lowers overall production cost.
