Widely used as an antioxidant in plastics, this chemical prevents degradation caused by heat and oxidation during processing and long-term use. It is especially effective in polyolefins such as polyethylene and polypropylene, helping to maintain mechanical strength, color, and flexibility over time. Commonly added to films, containers, and outdoor plastic products exposed to high temperatures or UV radiation. Also used in adhesives, sealants, and rubber to extend service life by inhibiting oxidative aging. Compatible with other stabilizers, allowing synergistic performance in complex stabilization systems.
