Used primarily as an antioxidant in plastics, rubber, and adhesives to prevent degradation from heat and oxidation. It helps extend the lifespan of polymer-based materials by inhibiting the formation of free radicals. Commonly found in industrial applications where thermal stability is required during processing or long-term use. Also utilized in lubricants and greases to maintain performance under high-temperature conditions. Its effectiveness in low concentrations makes it suitable for formulations requiring minimal additive content.
