Patent ID: 8841367

Claim:
A flame retardant composition comprising: a polycarbonate; 5 to 10 weight percent of a polysiloxane-polycarbonate copolymer; where the polysiloxane-polycarbonate copolymer comprises an amount of greater than 10 weigh percent of the polysiloxane and where the weight average molecular weight of the polysiloxane-polycarbonate copolymer is greater than or equal to 25,000 grams per mole; 5 to 20 weight percent of a branched polycarbonate; 5 to 60 weight percent of a reinforcing filler; and 1 to 15 weight percent of a flame retardant compound; where all weight percents are based on the total weight the flame retardant composition; flame retardant composition has notched Izod impact strength of 100 to 140 Joules/meter.
