Used as a high-performance antioxidant in polymers, particularly in polyolefins and engineering plastics, due to its ability to protect materials from thermal and oxidative degradation during processing and long-term use. Its sterically hindered structure enhances stability and effectiveness at elevated temperatures. Commonly applied in automotive components, electrical insulation, and industrial films where extended service life and resistance to aging are critical. Also utilized in specialty adhesives and coatings requiring improved durability under harsh environmental conditions. Shows compatibility with other stabilizers, allowing synergistic formulations for enhanced protection.
