TWO NEW HITRILE RDIBERS WE'VE TESTED TO THE SOOTH HEGBEE I F.I They're ready—two new nitrile rubbers that aren't just any ordinary polymers. They're specially prepared and coagu lated to give them excellent corrosionto-metal resistance, and other vital properties you need to make the best seals. We've conducted extended 300° F. aging tests, and they're proving that the heat and oil resistance capability of these remarkable new compounds is significantly higher than conventional
compounds (with a cadmium oxide/ cadmium diethyldithio carbamate cur ing system). Their scorch resistance is also ex tremely high. Both have a medium level of acrylonitrile, are non-staining, and are excellent for processing. F R - N 6 0 7 is 50-60 ML4@ 212°R Mooney. F f t - N 6 0 8 is75-90 ML4@ 212°F. Mooney.
If corrosion-to-metal is your problem, these two nitrile rubbers from Firestone may be your answer. They're important.
