Antioxidant 24(Cat No.:R028723), also known as N,N’-Hexane-1,6-diylbis(3,5-di-tert-butyl-4-hydroxybenzamide), is a high-performance phenolic antioxidant used to protect polymers and plastics from oxidative degradation. It features hindered phenol groups that scavenge free radicals, effectively stabilizing materials exposed to heat, oxygen, or UV light. Antioxidant 24 is particularly valuable in polyolefins, elastomers, and engineering plastics, where long-term thermal and oxidative stability is critical. Its low volatility and high molecular weight reduce migration and loss during processing, enhancing durability. This makes it ideal for automotive, packaging, and electrical applications requiring extended product lifespans.
