Used as a stabilizer in polymers and plastics, particularly in polyolefins, to prevent degradation caused by heat and oxidation during processing and long-term use. It effectively extends the service life of plastic products by protecting against UV-induced damage and thermal aging. Commonly found in packaging materials, automotive components, and industrial films where durability is critical. Also utilized in adhesives and sealants to maintain flexibility and strength over time. Its low volatility and good compatibility with various resins make it suitable for high-temperature processing applications.
