Widely used as a high-performance antioxidant in polymers, this compound effectively prevents thermal and oxidative degradation during processing and in end-use applications. It is especially effective in polyolefins such as polyethylene and polypropylene, where it maintains material integrity under high-temperature conditions. Its sterically hindered structure provides long-term stability by neutralizing free radicals, making it ideal for applications requiring extended service life under heat and stress. Commonly found in automotive parts, electrical insulation, and outdoor-exposed plastic products due to its excellent resistance to volatilization and extraction. Also used in adhesives, sealants, and elastomers to enhance durability and prevent discoloration.
