Title:
A polypropylene film and a film capacitor
Document Type and Number:
Japanese Patent JP6070864
Kind Code:
B2
Abstract:
A polypropylene film in which the sum of the breaking strength thereof in the principal-axis direction of the film measured at 125°C and the breaking strength in the direction orthogonal to the principal axis of the film is 250 MPa or greater. Provided is a polypropylene film capable of demonstrating excellent voltage resistance and reliability at a high temperature in a capacitor application for high voltage, and in which suitable thermal dimensional stability and high rigidity are obtained at the same time in such applications as the above-mentioned capacitor application.
