Abstract: front page image
(EN)A laminated porous film including a porous layer containing a heat-resistant material laminated on at least one surface of a porous layer containing a polyolefin, the laminated porous film satisfying the following equation (I). 0.1136 × α + 0.0819 × β + 3.8034 ≧ 4.40 (I); α: the film resistance value of the laminated porous film (Ω・cm2), β: the volume value (cc/m2) of the heat-resistant material contained per 1 m2 of the porous layer containing the heat-resistant material
(FR)L'invention concerne un film poreux stratifié dans lequel une couche poreuse contenant un matériau résistant à la chaleur, est stratifiée sur au moins une face d'une couche poreuse contenant une polyoléfine. Plus précisément, le film poreux stratifié de l'invention satisfait la formule (I) suivante : 0,1136×α+0,0819×β+3,8034≧4,40 (I) α : valeur de la résistance membranaire (Ω.cm2) du film poreux stratifié ; β : volume apparent (cc/m2) du matériau résistant à la chaleur contenu dans 1m2 de couche poreuse contenant le matériau résistant à la chaleur.
(JA)ポリオレフィンを含む多孔質層の少なくとも片面に、耐熱性材料を含む多孔質層が積層された積層多孔質フィルムであって、下記式(I)を満足する積層多孔質フィルム。 0.1136×α+0.0819×β+3.8034≧4.40 (I) α:積層多孔質フィルムの膜抵抗値(Ω・cm) β:耐熱性材料を含む多孔質層1mあたりに含まれる耐熱性材料の体積値(cc/m
