Used as a stabilizer in polymer systems, particularly in plastics and synthetic rubbers, to prevent degradation caused by heat and oxidation. Its structure allows it to act as an antioxidant by scavenging free radicals that form during thermal processing and long-term aging. Commonly applied in polyolefins, such as polyethylene and polypropylene, to maintain mechanical properties and color stability during extrusion, molding, and prolonged use. Also found in adhesives and sealants where extended service life under thermal stress is required. Shows compatibility with other stabilizers, enabling synergistic effects when combined with secondary antioxidants like phosphites or thioethers.
