Used as a high-performance antioxidant in polymers and elastomers, particularly in rubber and plastic systems where thermal and oxidative stability are critical. Its sterically hindered structure provides excellent resistance to degradation under high-temperature processing and prolonged aging. Commonly employed in automotive rubber components, wire and cable insulation, and industrial molded parts to extend service life by preventing oxidative chain scission and crosslinking. Also utilized in specialty lubricants and greases to inhibit sludge formation and maintain viscosity stability under severe operating conditions. Shows low volatility and good compatibility with non-polar matrices, making it suitable for long-term stabilization in demanding environments.
