Used as an effective antioxidant and stabilizer in polymers, particularly in polyurethane systems. It protects against thermal and oxidative degradation during processing and extends the service life of the final product. Commonly added to flexible and rigid foams, elastomers, adhesives, and coatings to maintain physical properties and prevent discoloration. Also functions as a secondary stabilizer in combination with primary antioxidants in plastics, enhancing performance under high-temperature conditions. Its hydrolytic stability makes it suitable for applications exposed to moisture.
