Typical Properties

Product Form:                     Solid

Melting Range:                   49 – 54oC

Molecular Weight:              530.9 g/mol


BNX 1076 is a highly effective antioxidant and process stabilizer in polyolefins, including polyethylene, polypropylene, polybutene, and in olefin copolymers such as EVA. It also provides excellent performance in other polymers such as styrenic polymers (including PS, HIPS, ABS, and block copolymers), polycarbonate, acrylics, polyurethanes, PVC, and polyvinylidene chloride. BNX 1076 is also recommended for use in adhesives, elastomers, urethane and acrylic coatings, and many other organic substrates.


  • Provides excellent stability during high temperature processing and long term heat aging
  • Compatible with a wide range of organic substances
  • Easily incorporated by melting techniques due to its low melting point
  • Non-staining and non-discoloring
  • Odorless and tasteless
  • Low volatility
  • Extensive FDA clearances
  • Compatibility with other stabilizers and additives

Guidelines for Use

Recommended loading concentrations range between 0.05% and 0.5% in polyolefins, between 0.05 and 0.2% in other polymers, between 0.2% and 1% in hot melt adhesives, and between 0.1% and 0.5% in synthetic tackifier resins. Combinations of BNX 1076 with other antioxidants such as phosphites and thioethers often show synergistic performance. BNX 1076 is also suitable for use in combination with light stabilizers, including hindered amine light stabilizers (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. Please contact Mayzo for specific recommendations.


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.


Please consult the Safety Data Sheet (SDS) prior to handling or using this product.
