A composition comprising a blend of: a) one or more polycarbonates; b) one or more polyesters; c) one or more core shell rubbers having glycidyl groups on the surface of the core; and d) one or more halogenated fire retardant agent; wherein the polycarbonates and polyesters form separate phases and the core shell rubber is located in the polyester phase. The compositions may further comprise a fluoropolymer capable of functioning as an anti-drip agent. The compositions exhibit a flame retardant rating according to UL-94 at V-0 of 3.0 mm or less; a notched Izod impact strength of about 8 foot pounds per inch or greater and chemical resistance to one or more of the common cleaning compositions selected from bleach, polyethylene glycol, a mixture of aryl substituted phenols and aryl substituted chlorophenols, a mixture of an alkanol and a monoalkyl ether of ethylene glycol, and one or more ammonium chlorides.
