Abstract
A composition containing a polycarbonate, a polycarbonate-polysiloxane copolymer, an alicyclic hydrocarbon resin flow promoter, an inorganic filler, a flame retardant and an impact modifier. The compositions may include polycarbonate in an amount of 40% by weight or more of the combined weights of the polycarbonate, polycarbonate-polysiloxane copolymer, inorganic filler, flame retardant, flow promoter, and impact modifier compound wherein a molded sample of the thermoplastic composition is capable of achieving UL94 V0 rating at a thickness of 1.2 mm (±10%); wherein the polymer composition has a melt viscosity of 185 Pa·sec or less, when measured at 270° C. and 1500 sec; and wherein a molded sample of the thermoplastic composition has a flexural modulus determined in accordance with ASTM D790 within 3800-8000 MPa; and wherein a 3.2-mm thick molded NII bar comprising the composition has a notched Izod impact strength of 40 to 200 J/m determined in accordance with ASTM D256 at 23° C.
