Polyvinyl Chloride (PVC) is a remarkably versatile polymer, but its susceptibility to degradation upon exposure to heat, light, and oxygen presents a significant challenge in its processing and application. Understanding the science of PVC stabilization is paramount for manufacturers aiming to produce durable, high-quality PVC products. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer in China, is dedicated to advancing the field of PVC stabilization through innovative plastic additives.

At its core, PVC degradation involves the elimination of hydrogen chloride (HCl) molecules, a process known as dehydrochlorination. This release of HCl can catalyze further degradation, leading to a chain reaction that results in discoloration, embrittlement, and ultimately, product failure. Stabilizers work by interfering with this process in various ways. Some act as scavengers for free HCl, while others interrupt the radical chain reactions that initiate degradation or absorb UV radiation that can trigger decomposition.

Our expertise at NINGBO INNO PHARMCHEM CO.,LTD. lies in developing advanced stabilizer systems, such as our Calcium Zinc (CaZn) based formulations. These systems are highly effective and offer an environmentally conscious alternative to traditional heavy metal-based stabilizers. The science behind CaZn stabilizers involves synergistic combinations of calcium and zinc stearates, often with organic co-stabilizers, which work together to provide excellent heat stability and prevent dehydrochlorination. This makes them ideal for a wide range of PVC applications, from rigid pipes to flexible films and cables.
