Abstract:
A composition comprising: a first polycarbonate comprising a poly(siloxane-carbonate); a second polycarbonate different from the first polycarbonate; and optionally, a third polycarbonate different from the first and second polycarbonate; wherein the first polycarbonate is present in an amount effective to provide the siloxane units of in the first polycarbonate in an amount of at least 0.3 wt %, and the second polycarbonate is present in an amount effective to provide the bromine of the second polycarbonate in an amount of at least 7.8 wt %; and further wherein an article molded from the composition has an OSU integrated 2 minute heat release test value of less than 65 kW-min/m2 and a peak heat release rate of less than 65 kW/m2, and an E662 smoke test Dmax value of less than 200.
