Application of Additives in PVC Pipes and Fittings

PVC pipes and fittings are among the most important products in water supply, sewage, and construction industries. The final quality of these products strongly depends on the right choice of PVC pipe additives. Using specialized additives not only improves durability and mechanical strength but also ensures smoother and more cost-efficient processing

Calcium-zinc and lead-based stabilizers, as the main additives in this industry, ensure thermal stability and stable color. After that, polymer waxes including polyethylene wax (PE Wax) and paraffin and the role of external lubricant and products similar to G60 play the role of internal lubricant and create shiny and white-free surfaces by reducing energy consumption and consumption.

Impact modifiers such as CPE and AIM enhance mechanical strength and improve resistance to pressure and external shocks. In addition, acrylic processing aids promote better fusion, uniform gelation, melt stability, and high-quality surface finish. Complementary additives complete the formulation: titanium dioxide improves brightness and coverage, calcium carbonate increases rigidity and supports cost optimization, and optical brighteners enhance whiteness and product appearance
