MD-1097 is a sterically hindered phenolic antioxidant and metal deactivator. BNX. MD-1097 protects polymers against oxidative degradation and metal catalyzed degradation during processing and in end-use applications. This antioxidant also provides long term thermal 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. BNX. MD-1097 will stabilize polypropylene, polyethylene, polystyrene, polyester, EPDM, EVA and ABS. Low volatility ,Strong synergistic effect with phosphites, other phenols and thioesters, Non-staining and non-discoloring,FDA approved for adhesives and polymerspackage： 25KG/drum，there is inner plastic bag in drum, or according to the requirement of the customersstorage： stored avoiding of high temperature and humidity.
