Abstract: Polycarbonate compositions comprising a linear homopolycarbonate, a poly(phthalate-carbonate), or a combination thereof; a poly(carbonate-siloxane) component present in an amount effective to provide 0.1 to 10 wt % siloxane, based on the total weight of the composition, comprising: a poly(carbonate-siloxane) having a 30-70 wt % siloxane content, a combination of a poly(carbonate-siloxane) having a 10 wt % or less siloxane content and a poly(carbonate-siloxane) having greater than 10 wt % to less than 30 wt % siloxane content, or a combination thereof; a linear polycarbonate comprising 0.1-4.0 mole % repeating units derived from a monomer having a pendant ester group based on the total moles of the composition; optionally, a reinforcing composition comprising glass fibers, a mineral filler, or a combination thereof; and a flame retardant comprising an aromatic organophosphorous compound can have low smoke density characteristics (e.g., a DS-4 measured according to ISO5659-2) and low heat release characteristics, (e.g., MAHRE measured according to ISO5660-1).

Abstract: A polycarbonate composition comprising: a polycarbonate comprising a homopolycarbonate, a poly(ester-carbonate-siloxane), a poly(aliphatic ester-carbonate), a poly(ester-carbonate-siloxane), a brominated polycarbonate, a poly(ester-carbonate), or a combination thereof and optionally, a poly(phthalate-carbonate); a poly(carbonate-siloxane) present in an amount effective to provide 1-10 wt % total siloxane, based on the total weight of the composition; 11-25 wt % of a reinforcing composition comprising 10-24 wt % glass fibers, and 1-10 wt % mineral filler comprising talc, kaolin, calcium carbonate, wollastonite, or a combination thereof; optionally, an organophosphorous flame retardant in amount effective to provide up to 1.5 wt % phosphorous; optionally, up to 10 wt % additive composition, wherein each amount is based on the total weight of the polycarbonate composition, which sums to 100 wt %.
