Ultradünner, poröser und mechanisch stabiler Vliesstoff und dessen Verwendung

摘要

An ultrathin, porous, and mechanically stable nonwoven fabric, a method for manufacturing the fabric, and the fabric's use are described. A nonwoven fabric is described having a thickness of less than 30 μm, which is chemically and/or thermally bonded, whose maximum tensile load in at least one direction is at least 15 N/5 cm, whose stretching in this direction at maximum tensile load is 35% at the most, and which has a porosity of at least 25%. This nonwoven fabric may be used as a separator material or as a carrier material for diaphragms.
