In the industrial production of polymer materials such as polypropylene (PP), high-temperature extrusion and high-shear processing conditions can easily trigger thermal oxidative degradation of the polymer, leading to problems such as yellowing, reduced mechanical properties, and cosmetic defects, which severely impact the quality of the finished product and its market competitiveness. Traditional antioxidants generally suffer from high dosage requirements, poor high-temperature resistance, limited anti-yellowing effectiveness, and low overall cost-effectiveness, making them ill-suited for the production demands of continuous high-temperature processing in large-scale equipment. JADEWIN AO136, a high-efficiency benzofuranone antioxidant, was developed to address these challenges. With its excellent free radical scavenging capacity, high activity at low loading levels, and exceptional synergistic effects, it has become the preferred additive for preventing oxidation and yellowing during high-temperature processing of polymer materials.
