MD-697 CAS 70331 94 1 Hindered phenolic antioxidants Thanox Md-697 equivalent
|Chemical Name||(1,2-Dioxoethylene)bis(iminoethylene) bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate)|
|Synonyms||ThanoxMd-697;Antioxidant MD-697;Antioxidant 697;|
This product possesses the double structures of hindered phenol and acyl,and afunction ofanti-oxidation and metal deactivation. This product is a kind of metaldeactivator, can be used either independently or together with antioxidant. Itis applicable to polyethylene, polypropylene, polystyrene, polyamide,polyester, and especially to the antioxidant used in phenolic resin. It iseffectively preventing the polymeric substance from self-oxidation caused bytransition metal ion (the remains of the catalyst). More efficient if it isadded to the polymeric substance used in insulated electric wire and cable .Theperfect melting nature makes it easily to mix withand into the substancementioned above and other polymeric substance system without any dispersingproblem. The general dosage is of 0.1-0.5 share.
697 is a sterically hindered phenolic antioxidant and metal deactivator.697 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 polymers.
