Used primarily as an antioxidant in organic materials, especially in polymers and plastics, to prevent degradation caused by oxidation. It helps extend the service life of products by stabilizing them against thermal and oxidative stress during processing and long-term use. Commonly found in polyolefins such as polyethylene and polypropylene, it maintains material integrity, preventing discoloration, embrittlement, and loss of mechanical strength. Also applied in adhesives, sealants, and elastomers where thermal stability is required. Its moderate volatility makes it suitable for processing at elevated temperatures.
