POLYPHENYLENE SULFIDE LAMINATED FILM FOR CAPACITOR AND CAPACITOR USING THE FILM

摘要

PROBLEM TO BE SOLVED: To improve voltage resistance, which has been a problem for a PPS film excellent in capacitor properties such as heat resistance and dielectric properties, without deteriorating the processability of a capacitor. SOLUTION: A polyphenylene sulfide laminated film for capacitors in which a layer comprising an amorphous polyester resin composition of at least 150 deg.C softening temperature is laminated at least on one side of a polyphenylene sulfide film and a capacitor made by a process in which a metal layer are formed at least on one side of the laminated film and they are wound or laminated.
