ABSTRACT:
Disclosed herein is a thermoplastic composition comprising:a polycarbonate;an impact modifier;a polycarbonate-polysiloxane copolymer;a poly(arylene ether)-polysiloxane copolymer; andan organophosphate in an amount of 2 to 20 weight percent based on the combined weight of polycarbonate, impact modifier, polycarbonate-polysiloxane copolymer, and poly(arylene ether)-polysiloxane copolymer,wherein the composition has a notched Izod impact strength of greater than or equal to 4 kilojoules per square meter (kJ/m2) as determined according to ISO 180/A, a melt viscosity rate of less than or equal to 130 Pascal seconds (Pa·s) as determined according to ISO11443 at 1500 s−1and 280° C., and a UL94 rating of V1 or better at 0.8 millimeter thickness.
