A thermoplastic composition includes: 40 to 75 wt % of a poly(carbonate-siloxane-arylate); 5 to 45 wt % of a poly(carbonate-siloxane) present in an amount effective to provide 0.75 to 7 wt % of siloxane units; 10 to 40 wt % of a polycarbonate homopolymer; 5 to 15 wt % of an organophosphorus compound in an amount effective to provide 0.1 to 1 wt % of phosphorus; and optionally, 0.1 to 10 wt % of an additive composition. The thermoplastic composition has a melt volume flow rate of greater than 6 cm/10 min. An article molded from the thermoplastic composition has a 2-minute integrated heat release rate of less than or equal to 65 kW-min/mand a peak heat release rate of less than 65 kW/mand a notched Izod impact resistance of greater than 30 kJ/mor greater than 700 J/m.

Thermoplastic compositions, methods of their manufacture, and articles thereof

A thermoplastic composition comprises, based on the total weight of the polymers in the thermoplastic composition, a polycarbonatesiloxane-arylate; 2 to 15 wt % or 2 to 8 wt % or 1 to 4 wt % of a core-shell impact modifier; a flame retardant comprising a bromine-containing polymer or oligomer effective to provide 1.5 wt % to 5 wt % of bromine; an aromatic organophosphorus compound, effective to provide 0.1 to 1 wt % of phosphorus, or a combination comprising at least one of the foregoing; and optionally 0 to 80 wt % or 0 to 60 wt % of a polyetherimide.
