Polyvinyl Chloride (PVC) is one of the most widely used polymers globally, found in applications ranging from construction materials to consumer goods. The polymerization process for PVC is complex, and controlling it effectively is key to achieving desired material properties. In this context, specialized additives like Antioxidant 245 play a crucial, albeit often overlooked, role. Known by its CAS number 36443-68-2, Antioxidant 245 serves not only as a stabilizer but also as an effective chain terminator in PVC polymerization.

For manufacturers involved in PVC production, understanding the functions of each additive is vital for process optimization and product quality. Antioxidant 245, a sterically hindered phenolic antioxidant, is primarily recognized for its ability to prevent thermal-oxidative degradation. However, its utility in controlling the polymerization process itself is equally significant. As a chain terminator, it helps to regulate the molecular weight and distribution of the PVC chains, influencing crucial properties such as melt flow, processing temperature, and mechanical strength.

The incorporation of Antioxidant 245 during PVC polymerization offers several advantages. By capping growing polymer chains, it helps to prevent excessively high molecular weights, which can lead to processing difficulties and undesirable rheological behavior. This control allows for more stable processing conditions and can contribute to improved product consistency. Manufacturers seeking to buy high-quality PVC resins will benefit from the use of such carefully selected additives.

Beyond its role as a chain terminator, Antioxidant 245 continues to provide its inherent stabilizing properties throughout the PVC product's lifecycle. Its low volatility and high extraction resistance ensure that the PVC material remains protected from degradation caused by heat and oxidation, thereby extending its service life and maintaining its appearance. This dual functionality makes Antioxidant 245 a cost-effective and efficient additive for PVC manufacturers.
