HIGH-POROSITY SEPARATOR FOIL |
摘要 |
The invention relates to a biaxially oriented single- or multilayer porous foil, the porosity of which is generated by transformation of ss-crystalline polypropylene during orientation of the foil. The Gurley value of the foil is <250 s. The invention also relates to a process for producing the foil by using a low transverse stretching velocity for the transverse orientation process. |
