LOWINOX® 22M46 stabilizer is a non-discoloring antioxidant based on a sterically hindered alkylated bis-phenol.
It 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.
