Used as a high-performance antioxidant and stabilizer in polymers, especially in polyolefins such as polyethylene and polypropylene. It protects materials from thermal, oxidative, and UV-induced degradation during processing and long-term use, maintaining mechanical properties and color stability. Commonly employed in cables, films, molded parts, automotive components, and electrical insulation exposed to high temperatures and outdoor conditions. Offers excellent resistance to heat aging, low volatility, and effective radical scavenging for light stabilization.
