Used as a high-performance antioxidant in polymers, especially in polyolefins such as polyethylene and polypropylene. It protects materials from thermal and oxidative degradation during processing and extends the service life of plastic products exposed to heat and light. Commonly added to cables, pipes, and automotive components where long-term stability is critical. Also effective in adhesives, sealants, and elastomers to prevent cracking and embrittlement. Shows excellent compatibility with other stabilizers, allowing synergistic formulations for enhanced protection.
