Used as a high-performance antioxidant in polymer systems, particularly in polyolefins and elastomers, to prevent thermal and oxidative degradation during processing and long-term use. Offers excellent protection against discoloration and molecular weight loss under high-temperature conditions. Commonly employed in wire and cable compounds, automotive components, and industrial rubber goods where thermal stability is critical. Also effective in lubricants and greases to extend service life by inhibiting oxidation and sludge formation. Shows good compatibility with other stabilizers, allowing synergistic formulations for enhanced durability.
