Used primarily as an antioxidant in polymers and plastics, protecting materials from degradation due to heat and oxidation during processing and long-term use. Commonly found in polyolefins such as polyethylene and polypropylene to enhance durability and extend service life. Also applied in rubber, adhesives, and sealants to maintain elasticity and prevent cracking. Effective in industrial lubricants and greases where thermal stability is required. Its hindered phenolic structure provides strong radical scavenging properties, making it suitable for stabilizing formulations exposed to high temperatures and harsh environments.
