A primary object of the present invention is to provide a film exhibiting high electrical insulation properties and excellent withstand voltage properties and a method for producing the film.
As a means for achieving the object, the present invention provides a vinylidene fluoride-based polymer film in which the 99% voltage failure resistance value in a Weibull plot is 300 V/µm or more.
本发明的主要目的是提供一种具有高电气绝缘性能和优异耐电压性能的薄膜以及生产该薄膜的方法。
作为实现上述目标的一种方法,本发明提供了一种偏氟乙烯基聚合物薄膜,在 Weibull 图中,该薄膜的 99% 耐电压失效值为 300 V/µm 或更高。
