OCN 4734

ANTIOXIDANT

Chemical Composition: Mixed Alkylated Hindered Phenols

 

Performance: Due to different alkyl chain length of hindered phenol groups it inhibits oxidation of all types of molecules having olefinic groups effectively. It has good  compatibility with all other types of additivies and gives synergistic effect along with Aminic typeantioxidants as compared to DBPC.
