An electrically insulating film having a total halogen content of about 1% to about 8%, comprising a resin component containing:a) from 0 to about 40 parts of a rubber selected from EP or EPDM rubber,b) correspondingly, from about 60 to about 100 parts of an ethylene vinyl acetate polymer,c) from about 20% to about 40% based on said resin component, of a flame retardant system comprisingi) from about 5 to about 25% of a bromine containing flame retardant,ii) from about 1.5% to about 10% of an antimony containing flame retardant, andiii) from 1% to about 20% of a flame retardant selected from granular metal oxide hydrates, wherein said flame retardant system has a ratio of metal oxide hydrate to bromine of no more than about 3;said film being free of vinyl chloride wherein a nonoriented film self-extinguishes in less than about 5 seconds, has an elongation at break of at least about 500%, a dielectric strength of at least about 1200 V/Mil, and a stress-strain curve having a wholly positive slope.
