BNX® 549 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.

Applications:
BNX® 549 is particularly useful for the stabilization of plastics and elastomers derived from butadiene and other dienes, for example polybutadiene and copolymers of polybutadiene and other monomers. The product is also effective in the stabilization of polyolefins and polyamides.

Advantages:

• Highly effective to prevent gel formation in butadiene homo- and co-polymers, especially under anaerobic conditions

• Non-discoloring and low volatility

• FDA-cleared for use in polypropylene, styrenic block copolymers, polystyrene, and rubber-modified polystyrene
