Calcium Zinc Compound Stabilizer For PVC Window Profile

PVC window profiles are a common building material that has excellent Weather resistance, corrosion resistance, and mechanical strength, making them widely used in the construction industry. However, PVC materials are susceptible to factors such as thermal decomposition, oxidation, and photolysis during processing and use, resulting in a decrease in their performance and shortened lifespan.
In order to improve the stability and service life of PVC window profiles, calcium zinc composite stabilizers have become a commonly used additive. Calcium zinc composite stabilizers are composed of calcium and zinc salts, which chemically react with chlorine atoms in polyvinyl chloride molecules to form stable compounds, thereby preventing the thermal decomposition and oxidation reactions of polyvinyl chloride materials.
