FLAME RETARDANT POLYCARBONATE COMPOSITIONS AND THIN-WALL ARTICLES MADE THEREFROM

A flame retardant composition comprising: 34-94 wt % of a homopolycarbonate, acopolycarbonate, or a combination thereof; 5-85 wt % poly(carbonate-siloxane), in an amount effective to provide 2-6 wt % dimethyl siloxane; 0.05-0.6 w t%, preferably 0.2-0.4 wt%, of a C1-16 alkyl sulfonate salt flame retardant; 1-15 wt % of a mineral-filled silicone flame retardant synergist; 0.05-0.5 wt % of an anti-drip agent; wherein each amount is based on the total weight of the flame retardant composition, which sums to 100 wt %; and wherein a molded sample of the flame retardant composition has a Vicat softening temperature of greater than or equal to 140° C. as measured according to the ISO-306 standard at a load of 10 N and a heating rate of 50° C. per hour, and a flame test rating of V0 as measured according to UL-94 at a thickness of 1.0 millimeter, or at a thickness of 0.8 millimeter.
