Stronger Heat Control, Longer Life — The High-Performance Advantage of Ca-Zn Stabilizer C-60

Ca-Zn Stabilizer C-60 is an advanced calcium-zinc heat stabilizer developed for PVC applications that require higher thermal endurance, processing stability, and long-term performance. Designed as an eco-friendly alternative to traditional heavy-metal stabilizers, C-60 delivers reliable protection during high-temperature processing while supporting cleaner production and compliance with increasingly strict environmental standards.

The key strength of Ca-Zn Stabilizer C-60 lies in its enhanced heat resistance and excellent dynamic stability. It effectively delays PVC degradation, discoloration, and molecular breakdown during extrusion, injection molding, and calendaring, even under demanding processing conditions. The formulation provides balanced internal and external lubrication, ensuring smooth fusion, stable melt flow, and improved surface finish. Finished products show consistent color, good gloss, strong mechanical properties, and superior aging resistance.


In practical applications, Ca-Zn Stabilizer C-60 is widely used in rigid PVC products such as pipes, fittings, profiles, sheets, and cable insulation. For example, in continuous pipe production lines operating at high output, C-60 maintains a wide processing window and stable product dimensions over long runs. In profile and sheet manufacturing, it supports clean surfaces and uniform appearance, reducing defects and improving overall production efficiency.

For customers, Ca-Zn Stabilizer C-60 directly addresses pain points such as insufficient heat stability, narrow processing tolerance, frequent color shifts, and pressure from environmental regulations. By offering stronger thermal protection without toxic heavy metals, it lowers scrap rates, reduces downtime, and simplifies process control. The result is a dependable, cost-effective stabilizer that helps manufacturers achieve higher productivity, consistent quality, and long-term competitiveness in global PVC markets.
