Claim 14:
15. A reinforced polycarbonate composition comprising
30-60 weight percent of a homopolycarbonate;
5-30 weight percent of a poly(carbonate-siloxane);
10-40 weight percent of a high heat polycarbonate having a glass transition temperature of 170° C. or higher determined per ASTM D3418 with a 20° C./min heating rate and comprising a poly(ester-carbonate) comprising bisphenol A carbonate units, and aromatic ester units derived from bisphenol A;
1-10 weight percent of a phosphorous-containing flame retardant present in amount effective to provide 0.1-1.5 weight percent phosphorous;
0.01-0.5 weight percent of an anti-drip agent;
5-30 weight percent of a reinforcing fiber; and
optionally, up to 10 weight percent of an additive composition,
wherein each amount is based on the total weight of the reinforced polycarbonate composition, which sums to 100 weight percent; and
wherein a molded sample of the polycarbonate composition has
a heat deflection temperature of greater than 115° C., as measured according to ISO 75 at 0.45 megapascal, or
a flame test rating of V1 as measured according to UL-94 at a thickness of 0.8 millimeter.
