ANTIOXIDANT HONOX-697 is a sterically hindered phenolic antioxidant and metal deactivator. It protects polymers against oxidative degradation and metal catalyzed degradation during processing and in end-use applications. It also provides long term thermal stabilization properties. It has low volatility. It is an excellent, non-discoloring, non-staining antioxidant and thermal stabilizer with outstanding metal deactivation properties.

It is highly effective to prevent the harmful effects of copper conductors in polymers used as primary wire and cable insulation, including polypropylene, high-density and low-density polyethylene, ethylene-vinyl acetate copolymers and some thermoplastic elastomers. It is also used for other polymer systems where contact with metals may affect polymer properties and stability, including polystyrene, polyesters and others. Strong synergistic effect with phosphites, other hindered phenols and thioesters. FDA approved for adhesives, polystyrene and olefin polymers. info at hhochem. com
