Title
(EN) ORIENTED POLYESTER FILM
(FR) FILM DE POLYESTER ORIENTÉ
(JA) 配向ポリエステルフィルム
Abstract
(EN)
Provided is an oriented polyester film having a layer (P1 layer) that contains polyester and a filler, wherein the P1 layer satisfies (1) and (2) below, whereby the oriented polyester film has exceptional electrical insulating properties and thermal conductivity. (1) The filler content in the P1 layer relative to the entire P1 layer is 10-60% by mass. (2) The polyester of the P1 layer has as a main component a polyester having an aromatic dicarboxylic acid component and a diol component as main structural components, the diol component including both a diol (A) having an even number of main chain carbon atoms and a diol (B) having an odd number of main chain carbon atoms, and the molar ratio (A)/(B) of the diol (A) and the diol (B) being 30/70-97/3.
(FR)
L'invention concerne un film de polyester orienté présentant une couche (couche P1) qui contient un polyester et une charge, la couche P1 satisfaisant à (1) et (2) ci-dessous, le film de polyester orienté présentant des propriétés d'isolation électrique et une conductivité thermique exceptionnelles. (1) La teneur en charge dans la couche P1 par rapport à la couche P1 entière est de 10 à 60 % en masse. (2) Le polyester de la couche P1 présente, comme constituant principal, un polyester présentant un constituant acide dicarboxylique aromatique et un constituant diol en tant que constituants structuraux principaux, le constituant diol comprenant à la fois un diol (A) présentant un nombre pair d'atomes de carbone de chaîne principale et un diol (B) présentant un nombre impair d'atomes de carbone de chaîne principale et le rapport molaire (A)/(B) du diol (A) et du diol (B) étant de 30/70 à 97/3.
(JA)
ポリエステルとフィラーを含有する層(P1層)を有する配向ポリエステルフィルムであって、前記P1層が下記(1)および(2)を満たす配向ポリエステルフィルムにより、電気絶縁性および熱伝導性に優れる配向ポリエステルフィルムを提供する。 (1)P1層のフィラーの含有量がP1層全体に対して10~60質量%であること。 (2)P1層のポリエステルが芳香族ジカルボン酸成分とジオール成分を主たる構成成分とするポリエステルを主成分とし、該ジオール成分が、主鎖炭素数が偶数のジオール(A)と、主鎖炭素数が奇数のジオール(B)の両方を含み、前記ジオール(A)とジオール(B)のモル比(A)/(B)が30/70~97/3であること。
