Used as a high-performance antioxidant in lubricants and polymers, particularly effective in preventing thermal and oxidative degradation in engine oils and industrial greases. It helps extend the service life of lubricants by inhibiting sludge formation and reducing viscosity changes under high-temperature conditions. Also employed in plastic and rubber manufacturing to maintain material integrity during processing and long-term use. Shows excellent compatibility with synthetic base stocks and additive packages, making it suitable for advanced automotive and aerospace applications.
