Title:
BIAXIALLY ORIENTED POLYPROPYLENE FILM FOR CAPACITOR, METAL LAMINATED FILM, AND FILM CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2016/158590
Kind Code:
A1
Abstract:
A biaxially oriented polypropylene film for a capacitor, in which µdm and µdt are each in the range of 0.60-1.70 and the value of the ratio (µdm/µdt) of µdm and µdt is 0.75 to less than 1.15, where µdm is the kinetic friction coefficient in a longitudinal direction and µdt is the kinetic friction coefficient in a width direction, and the film thickness measured by a micrometer method is in the range of 0.5-3 µm. Provided is a biaxially oriented polypropylene film for a capacitor, whereby excellent withstand voltage is demonstrated in a capacitor application, and stable productivity and workability are ensured.
