Used as a high-performance antioxidant in rubber and polymer systems, particularly in tires and industrial rubber goods. Provides excellent protection against ozone and flex cracking, enhancing the durability and lifespan of rubber products exposed to dynamic stress and outdoor environments. Commonly employed in passenger car tires, truck tires, and conveyor belts due to its ability to maintain mechanical properties under prolonged oxidative conditions. Also shows synergistic effects when combined with other antioxidants like hindered phenols and thioesters.
