Used as a high-performance antioxidant in polymers, especially in polyolefins and engineering plastics, to prevent thermal and oxidative degradation during processing and long-term use. Offers excellent stability under high-temperature conditions and improves the lifespan of plastic products exposed to heat and UV light. Commonly found in automotive components, electrical insulation, and industrial materials where thermal resistance is critical. Also utilized in adhesives and coatings to enhance durability and resistance to environmental aging.
