Antioxidant 24 is useful in the synthesis of polymer film composites such as polypropylene and polyethylene film materials. During the manufacturing and processing of polymers, exposure to heat and mechanical stress can induce oxidative degradation. Antioxidant 24 is added to plastics, rubber, and other polymer materials to protect them against heat and shear-induced oxidation. By preventing oxidative degradation, Antioxidant 24 extends the useful life of products made from these polymers, which include automotive parts and packaging materials. Antioxidant 24 is used in research to understand better the oxidative degradation mechanisms in polymers.
