MSDS Information
2,2'-Methylenebis(6-tert-butyl-4-methylphenol) Usage And Synthesis
UsesLOWINOX® 22M46 stabilizer is a non-discoloring antioxidant based on a sterically hindered alkylated bis-phenol.
UsesIt may be incorporated into the bromobutyl rubber(BIIR) matrix to enhance the overall thermo-reversibility of dicyclopentadiene dicarboxylic acid (DCPDCA) cross-linked BIIR. It may also be used as an antioxidant which shows a higher oxidation stability in distilled biodiesel.
DefinitionChEBI: 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) is a diarylmethane.
General Description2,2′-Methylenebis(6-tert-butyl-4-methylphenol) is a phenolic antioxidant commonly used in increasing the oxidation stability in rubber and plastic industries.
