3,3'-Bis(3,5-di-tert-butyl-4-hydroxyphenyl) -N,N'-hexamethylenedipropionamide
Structure：AO3398 is a hindered phenolic antioxidant, mainly be used in polyamide materials
·None discoloring
·Lower volatility
·Excellent extraction resistance in hot water · Excellent synergistic effect with secondary antioxidants
·Excellent compatibility with polyamide
AO3398 is an excellent antioxidant for polyamide fibers, molded articles and films. It can be added to protect polymer color properties during polymerization, manufacture, transportation and application period. AO3398 also can be manufactured as masterbatch, and show batter effects than the traditional antioxidants (1010,1076) in the polyamide .
