COMPOSITE POROUS FILM AND METHOD FOR PRODUCING SAME |
摘要 |
Provided is a composite porous membrane that simultaneously provides excellent adhesion of a heat-resistant resin layer and a small rising range of air resistance. The composite porous membrane of the present invention is a composite porous membrane, wherein a porous membrane B comprising a heat-resistant resin is laminated on the surface of a polypropylene resin of an outermost layer of a porous membrane A composed of at least one layer, wherein at least one of the outermost layers comprises the polypropylene resin. The composite porous membrane is characterized by satisfying a particular range of peeling strength at the interface between the porous membrane A and the porous membrane B and a particular range of difference between air resistance of the whole composite porous membrane and air resistance of the porous membrane A, provided that the porous membrane A satisfies a particular range of average pore size and porosity. |
