Used as a high-performance antioxidant in polymers and organic materials. It effectively prevents thermal and oxidative degradation during processing and long-term use, especially in engineering plastics, rubber, and adhesives. Its sterically hindered phenolic structure provides excellent stability at elevated temperatures and extends the service life of materials exposed to heat and oxygen. Commonly employed in automotive components, industrial coatings, and electrical insulation where durability is critical. Also utilized in specialty formulations requiring UV stabilization and color retention.
