Abstract
A film having a dielectric dissipation factor at a frequency of 1 kHz and 160° C. of 0.02% or lower and a dielectric breakdown strength at 160° C. of 400 V/μm or higher. Also disclosed is a film including at least one fluoropolymer selected from a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer and a tetrafluoroethylene/hexafluoropropylene copolymer, the fluoropolymer having a crystallinity of 65% or higher.
