Widely used as an antioxidant in plastics, coatings, and rubber products to prevent degradation caused by oxidation. It helps extend the service life of materials exposed to heat, light, and oxygen. Commonly added during polymer processing to maintain mechanical properties and color stability. Also found in adhesives and sealants where long-term durability is required. Effective in high-temperature applications due to its thermal stability. Used in combination with other antioxidants for synergistic effects in polyolefins and elastomers.
