A thermoplastic composition includes 35-95 weight percent of a poly(etherimide-siloxane) copolymer having a siloxane content of more than 0 to less than 50 weight percent based on the total weight of the poly (etherimide-siloxane) copolymer, 5-65 weight percent of a polyester, and 0-20 weight percent of one or more additives, wherein the weight percent of each component is based on the combined weight of the polymer components. An electrical wire including a wire conductor and a coating including the thermoplastic composition and an article including the electrical wire are also described.
