Abstract: A polycarbonate composition comprises: a first poly(carbonate-siloxane) copolymer, comprising a polysiloxane block with an average block length of 10 to 100, and a siloxane content from 5 wt % to 10 wt %; and a second poly(carbonate-siloxane) copolymer comprising a polysiloxane block with an average block length of 10 to 100, and a siloxane content from 30 wt % to 60 wt %; wherein the weight ratio of the first poly(carbonate-siloxane) copolymer to the second poly(carbonate-siloxane) copolymer is greater than or equal to 2 to less than 8; and a bisphenol A homopolycarbonate, wherein the polycarbonate composition has a total siloxane content of 2.5 wt % to 10 wt % based on the total weight of the composition; and a molded part of 1 mm thickness has a haze of less than 10% as measured by HazeGard (ASTM D1003-00).

Abstract: A poly(siloxane) copolymer composition comprising: a first polymer comprising a first repeating unit, and a poly(siloxane) block unit, a second polymer different from the first polymer and comprising of bromine; and optionally, one or more third polymers different from the first polymer and second polymer; wherein siloxane units are present in the composition in an amount of at least 0.3 wt %, and bromine is present in the composition in an amount of at least 7.8 wt %, each based on the sum of the wt % of the first, second, and optional one or more third polymers; 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.
