Title (EN) POROUS FILM AND MULTILAYER POROUS FILM
(FR) FILM POREUX ET FILM POREUX MULTICOUCHE
(JA) 多孔膜及び多層多孔膜
Abstract: front page image
(EN)Provided is a multilayer porous film having a porous film that contains a polyolefin-based resin as a primary component, and a porous layer that contains an inorganic filler and a resin-based binder laminated on at least one surface of the porous film. In the porous film, the average pore diameter (d) calculated using a gas-liquid method, the path curvature (τa), and the number of pores (B) are respectively d = 0.035-0.060 μm, τa = 1.1-1.7, and B=100-500 pores/μm2, and the film thickness of the porous film is L=5-22 μm.
(FR)La présente invention concerne un film poreux multicouche comportant un film poreux qui contient une résine à base de polyoléfine en tant que composant primaire. L'invention concerne également une couche poreuse qui contient une charge technique inorganique et un liant à base de résine stratifiés sur au moins une surface du film poreux. Dans le film poreux, le diamètre de pore moyen (d) calculé en utilisant un procédé gaz-liquide, la courbure de chemin (τa), et le nombre de pores (B), sont respectivement : d = 0,035 - 0,060 μm, τa = 1,1 - 1,7, et B = 100 - 500 pores/μm2 ; et l'épaisseur de film du film poreux est L = 5 - 22 μm.
(JA) ポリオレフィン樹脂を主成分とする多孔膜と、前記多孔膜の少なくとも片面に積層された無機フィラーと樹脂製バインダを含む多孔層と、を有する多層多孔膜であって、 前記多孔膜の、気液法によって算出した平均孔径d、曲路率τa、及び孔数Bが、それぞれd=0.035~0.060μm、τa=1.1~1.7、B=100~500個/μmであり、かつ前記多孔膜の膜厚LがL=5~22μmである、多層多孔膜。
