Abstract

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.
