✦ Synopsis

Flame retardance and smoke suppression have been studied in three systems containing acrylonitrile butadiene styrene terpolymer, decabromobiphenyl, and (a) commercial metastannic acid, (b) laboratory-prepared metastannic acid and (c) anhydrous tin(IV} oxide. Values of limiting oxygen index and smoke density have been measured for a large number of compositions in each system. They have then been fitted by fourth-order polynomials and plotted in triangular diagrams. Optimum atomic ratios for all these synergistic systems were found to be: Br/Sn = 9, a value which is much higher than would be expected from stoichiometric calculations. The systems also possess significant smoke-suppressant effectiveness.
