Abstract

A polycarbonate composition including 10-50 wt% of a linear polycarbonate, a branched polycarbonate endcapped with p-cumyl phenol, or a combination thereof; 5-20 wt% of a polycarbonate-siloxane copolymer having a siloxane content of 30-70 wt%, present in an amount effective to provide 3-14 wt% siloxane repeating units based on the total weight of the composition; 40-60 wt% of a highly branched polycarbonate endcapped with 4-hydroxybenzonitrile; 0.5-15 wt% of a non-fluorinated phosphorus-containing flame retardant; 0.1-5 wt% of a silicone fluid having dissolved therein a silicone resin; optionally, a colorant composition optionally comprising 0.1-10 wt% of TiO<2>; optionally, an additive composition; and optionally, 5-25 wt% of glass fibers; each based on the total weight of the polycarbonate composition, which totals 100 wt%; and wherein the polycarbonate composition comprises fluorinated compounds in an amount effective to provide 1500 ppm or less fluorine to the total composition; and wherein a molded sample of the polycarbonate composition has a UL-94 rating of 5V at a thickness of 3.0 millimeters
