A halogen-free electrically insulating film is prepared from a composition including particular amounts of a poly(arylene ether), a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and a triaryl phosphate. The electrically insulating film may be prepared by an extrusion and/or calendering method. Uses of the electrically insulating film include, for example, shielding applications in power supply housing, printed circuit board insulation, backlit aircraft in flight panels and displays, business equipment insulation, computer rack partitions, and television and monitor insulation.
