BNX® 549

• 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 rubbermodified polystyrene

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

The recommended loading levels in plastics and elastomers range between 0.05 and 0.5%. Best results in terms of processing and thermal oxidative stability are generally obtained by combining BNX 549 with conventional phenolic antioxidants and secondary antioxidants (phosphites, thiosynergists, and the like). BNX 549 can also be used in combination with light stabilizers such as HALS, UV absorbers, and benzoates. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use.

BNX 549 is cleared under 21 CFR §178.2010 for use as an antioxidant and/or stabilizer in polymers used in the manufacture of articles or components for use in food contact applications, including polypropylene, styrene block copolymers, and polystyrene (including rubber modified polystyrene). Please contact your Mayzo representative for complete details, including restrictions of use.

This product may be stored up to two years in a sealed container. Containers should be kept tightly closed when not in use and stored in a cool, dry place.
