Title (EN) POLYPROPYLENE FILM, METALLIZED FILM, AND FILM CAPACITOR
(FR) FILM DE POLYPROPYLÈNE, FILM MÉTALLISÉ ET CONDENSATEUR À FILM
(JA) ポリプロピレンフィルム、金属膜積層フィルムおよびフィルムコンデンサ
Abstract:
(EN) The purpose of the present invention is to provide a polypropylene film that exhibits high breakdown voltage even in high-temperature environments and, when made into a capacitor, is capable of offering voltage resistance and reliability even in high-temperature environments; a metallized film using the same; and a film capacitor. In order to achieve this goal, the surface on one side of this polypropylene film has a modulus of elasticity of at least 2.6 GPa as measured via nanoindentation, and the sum of the coefficients of thermal contraction in the lengthwise and widthwise directions of the film when heat-treated at 130°C for 10 minutes is 5% or less.
(FR) Le but de la présente invention est de fournir un film de polypropylène qui présente une tension de claquage élevée même dans des environnements à haute température et, lorsqu'il est transformé en un condensateur, est capable d'offrir une résistance à la tension et une fiabilité même dans des environnements à haute température ; un film métallisé l'utilisant ; et un condensateur à film. Pour atteindre cet objectif, la surface d'un côté de ce film de polypropylène a un module d'élasticité d'au moins 2,6 GPa tel que mesuré par nano-indentation, et la somme des coefficients de contraction thermique dans les directions dans le sens de la longueur et de la largeur du film lors du traitement thermique à 130 °C pendant 10 minutes est de 5 % ou moins.
(JA) 本発明は、高温環境下でも高い絶縁破壊電圧を示し、コンデンサとしたときに高温環境下でも耐電圧性および信頼性を発現できるポリプロピレンフィルム、それを用いた金属膜積層フィルムおよびフィルムコンデンサを提供することを目的とする かかる目的を達成するためのポリプロピレンフィルムは、フィルムの一方の表面をナノインデンテーション法で測定した弾性率が2.6GPa以上、フィルム長手方向および幅方向の130℃10分加熱処理における熱収縮率の和が5%以下である。
