BNX® 1900 is a synergistic blend of 20% BNX® 1076 and 80% Benefos® 1680. This blend of both a primary and secondary antioxidant provides excellent heat stability and antioxidation, with good compatibility with resins and excellent extraction resistance.

Applications: BNX® 1900 is a convenient blend of both a primary and secondary antioxidant. This synergistic blend addresses a broad range of stabilization needs. The phenolic antioxidant content provided by BNX® 1076 contributes synergistically to the polymer's stabilization and addresses applications requiring more long-term thermal stability by preventing thermo-oxidative degradation. The relatively high phosphite content of the secondary antioxidant, Benefos® 1680, addresses application with demanding processing conditions. In addition, Benefos® 1680 is particularly resistant to hydrolysis and provides protection to organic polymers that are prone to oxidation. This synergistic blend is primarily used in polyethylene and ethylene-copolymers such as ethylene-vinyl acetate copolymers. This blend can also be used in other polymers such as engineering plastics, polycarbonates, polyesters, styrene homo- and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates. BNX® 1900 can also be used in combination with light stabilizers to provide enhanced performance.
