POLYPROPYLENE FILM FOR CAPACITOR, METALLIZED POLYPROPYLENE FILM FOR CAPACITOR, AND CAPACITOR MADE OF SAME

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene film for a capacitor which is excellent in handling property when manufacturing a capacitor element, is excellent in withstand voltage characteristics, and is particularly appropriate for use of a small size with a large capacity.;SOLUTION: The polypropylene film for a capacitor comprises a single polypropylene resin layer wherein the difference of a surface gloss of one side from that of another side is 3-20%, and Δd (a thickness measured by a micrometer method minus a thickness measured by a mass method) of the film is 0.05-0.25 μm.;COPYRIGHT: (C)2007,JPO&INPIT
