Widely used as a stabilizer and secondary antioxidant in polymers to prevent degradation caused by heat, light, and oxidation. It is particularly effective in polyolefins, such as polyethylene and polypropylene, enhancing their longevity and maintaining mechanical properties during processing and end-use. It synergizes with primary antioxidants to improve overall performance in plastic formulations. Its applications extend to adhesives, coatings, elastomers (maintaining color stability and preventing embrittlement), synthetic fibers, and engineering plastics, ensuring durability and resistance to environmental stressors. Additionally, it serves as an additive in lubricants to reduce oxidation and extend service life, and in the rubber industry to prevent oxidative degradation, thereby improving rubber durability.
