AO-697 is a sterically hindered phenolic antioxidant and metal deactivator. AO-697 protects polymers against oxidative degradation and metal catalyzed degradation during processing and in end-use applications. This antioxidant also provides long-term thermally stabilization properties. This phenolic antioxidant is an excellent, non-discoloring, non-staining antioxidant and thermal stabilizer with outstanding metal deactivation properties. Typical end use applications include wire and cable insulation, film and sheet manufacture as well as automotive parts.
AO-697 is widely used in PP, PE, polystyrene, polyester, EPDM, EVA and ABS. It is of low volatility, non-staining and non-discoloring. It has strong synergistic effect with phosphites, other phenols and thioesters antioxidants. AO-697 is FDA approved for adhesives and polymers.
