BNX 549


BNX 549 (123968-25-2) is a multifunctional antioxidant for the stabilization of plastics and elastomers. Unlike conventional phenolic antioxidants, BNX 549 is effective to scavenge alkyl (carbon-centered) radicals. The product is particularly active under demanding processing conditions (high temperature, high shear) and under anaerobic conditions.
