Used as a secondary antioxidant in polyolefins, particularly in combination with primary antioxidants to enhance thermal stability during processing and long-term aging. It is highly effective in polyethylene and polypropylene applications, including films, fibers, and molded parts, where it prevents degradation caused by heat and shear stress. Commonly employed in wire and cable compounds due to its low volatility and good compatibility with stabilizer systems. Also utilized in food-contact compliant formulations owing to its low migration and regulatory acceptance.
