Abstract

The disclosure concerns blended thermoplastic compositions comprising (a) from about 50 wt % to about 80 wt % of a polycarbonate component; (b) from greater than 0 wt % to about 12 wt % of an impact modifier component; (c) from about 10 wt % to about 40 wt % of a filler; and (d) from about 5 wt % to about 15 wt % of a flame retardant component comprising an oligomeric phosphate ester, wherein the oligomeric phosphate ester is a free flowing powder at 23° C.; wherein the blended thermoplastic composition has a ductility of 100% at 10° C. when measured by a Notched Izod Impact test performed according to ASTM D256; wherein the combined weight percent value of all components does not exceed 100 wt %; and wherein all weight percent values are based on the total weight of the composition.
