Abstract:
A thermoplastic composition includes a poly(carbonate-arylate ester); and an organophosphorus compound in an amount effective to provide 0.1 to 1.0 wt % phosphorus based on the total weight of the composition, wherein an article molded from the composition has a smoke density after four minutes (Ds-4) of less than or equal to 300 determined according to ISO 5659-2 on a 3 mm thick plaque and a maximum average rate of heat release emission (MAHRE) of less than or equal to 90 kW/m2 determined according to ISO 5660-1 on a 3 mm thick plaque.
