Abstract: A polymer composition includes: about 20 wt % to about 80 wt % of a polycarbonate polymer; about 1 wt % to about 20 wt % of a polycarbonate-siloxane copolymer; about 15 wt % to about 35 wt % of a reinforcing filler having a tensile modulus of at least about 150 GPa; and about 4 wt % to about 20 wt % of a flame retardant comprising phosphorous. The polymer composition demonstrates a flexural modulus in an amount equal to or greater than about 10 GPa. Methods of forming a polymer composition and blended thermoplastic compositions are also described.
