AQUANOX® NB 4761 is specifically designed to give outstanding performance in the manufacture of NBR elastomer polymers. A synergistic blend of antioxidants ensures excellent heat ageing properties when added at suitable levels prior to coagulation. AQUANOX® NB 4761 is as a modern alternative to older 2246-based antioxidant products which are now considered as SVHC and too hazardous.
Addition is recommended in the range 0.5 to 1% as supplied, into a wet polymer dispersion or emulsion.
