Abstract:
Disclosed herein is 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 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 phosphazene compound. Disclosed herein too is a method comprising blending a polycarbonate; 5 to 10 weight percent of a polysiloxane-polycarbonate copolymer; 5 to 20 weight percent of a branched polycarbonate; 5 to 60 weight percent of a reinforcing filler; where the reinforcing filler is a glass fiber, a carbon fiber, a metal fiber, or a combination comprising at least one of the foregoing reinforcing fillers; and 1 to 15 weight percent of a phosphazene compound; and extruding the flame retardant composition.
