Abstract
This invention is directed to a molded electrical device comprising an electrically conductive pathway and an insulating material, and capable of interconnecting with external circuitry said insulating material comprising a blend of a particular amorphous polymer and a particular crystalline thermoplastic polymer. Also, this invention is directed to a composition suitable for use as an insulating material in an electrical device comprising from about 35 to about 65 weight percent of an amorphous polymer selected from a polyarylethersulfone resin, a polyarylether resin, a polyetherimide or a polyarylate, and from about 65 to about 35 weight percent of a crystalline polymer selected from a poly(arylene sulfide), a polyester or a polyamide.
