Benefos® 1680 is a phosphite type antioxidant of low volatility and extremely resistant to hydrolysis. This secondary antioxidant provides excellent heat stability and antioxidation, with good compatibility with resins and excellent extraction resistance. Benefos® 1680 performs best when combined with a primary antioxidant (i.e. BNX® 1010 or BNX® 1076).

Applications: This secondary antioxidant when combined with Mayzo's antioxidants, address a broad range of stabilization needs. Benefos® 1680, is an organophosphite of low volatility and particularly resistant to hydrolysis and provides excellent protection to organic polymers which are prone to oxidation. It is particularly useful in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polybutene and ethylene vinyl acetate copolymers as well as polycarbonate and polyamides. Other applications include use in linear polyesters, high impact polystyrene, ABS, SAN, adhesives, natural and synthetic tackifier resins, elastomers such as BR, IR, and other organic substrates. Benefos® 1680 can also be used in combination with UV absorbers and light stabilizers to provide enhanced performance.

Advantages: Extends performance of primary antioxidants (i.e. BNX® 1010 or BNX® 1076)
