Title
(EN) SEMIAROMATIC POLYAMIDE FILM AND METHOD FOR PRODUCING SAME
(FR) FILM DE POLYAMIDE SEMI-AROMATIQUE ET SON PROCÉDÉ DE PRODUCTION
(JA) 半芳香族ポリアミドフィルムおよびその製造方法
Abstract
(EN)
A semiaromatic polyamide film which is characterized in that: the thermal shrinkage ratio SMD in the film length direction and the thermal shrinkage ratio STD in the film width direction are from -1.0% to 1.5%, respectively as determined under the conditions of 250°C and 5 minutes; the tensile elongation at break in the length direction and the tensile elongation at break in the width direction are 70% or more, respectively; and the haze is 14% or less.
(FR)
Film de polyamide semi-aromatique caractérisé en ce que : le taux de retrait thermique SMD dans le sens de la longueur du film et le taux de retrait thermique STD dans le sens de la largeur du film sont compris entre -1,0 % et 1,5 %, respectivement déterminés dans les conditions de 250 °C et 5 minutes ; l'allongement en traction à la rupture dans le sens de la longueur et l'allongement en traction à la rupture dans le sens de la largeur sont de 70 % ou plus, respectivement ; et le trouble est inférieur ou égal à 14 %.
(JA)
250℃×5分条件下で測定される、フィルムの長手方向の熱収縮率SMDおよび幅方向の熱収縮率STDが、それぞれ-1.0~1.5%であり、長手方向および幅方向の引張破断伸度がそれぞれ70%以上であり、ヘーズが14%以下であることを特徴とする半芳香族ポリアミドフィルム。
