Abstract: 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 cm3/10 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/m2 and a peak heat release rate of less than 65 kW/m2 and a notched Izod impact resistance of greater than 30 kJ/m2 or greater than 700 J/m2.

Abstract: A polycarbonate composition comprises: a copolycarbonate comprising repeating units derived from a cyclohexylidene-bridged bisphenol; and an auxiliary polycarbonate comprising a branched homopolycarbonate; a poly(1,4-cyclohexanedimethylene terephthalate), a copolycarbonate derived from an isophorylidene-bridged bisphenol, and optionally a poly(alkylene cyclohexanedicarboxylate), poly(carbonate siloxane) having a siloxane content of less than 20 wt % based on the total weight of the poly(carbonatesiloxane), poly(aliphatic ester-carbonate) comprising bisphenol A carbonate units and C6-12 dicarboxy ester units; or a combination thereof. The polycarbonate compositions have one or more of a transparency of 89% or greater on 2.5 mm plaques according to ASTM-D1003-00; and a heat deformation temperature of at least 111° C., or at least 127° C. at 0.45 MPa or at least 98° C., or at least 110° C. at 1.82 MPa as determined on 3.18 mm bars per ASTM D648.
