Used as a stabilizer in polymer systems, particularly in polyolefins, to protect against degradation caused by heat and ultraviolet (UV) light. Its bulky aromatic structure enhances resistance to oxidation, making it effective in extending the service life of plastics exposed to harsh environmental conditions. Commonly found in automotive components, outdoor films, and industrial packaging where long-term stability is critical. Also employed in specialty formulations requiring high-performance additives with low volatility and good compatibility.
