    Abstract: The present invention relates to a filtration member (1) which is mainly used in a layered filter for forming a filter cake. A layer-settling structure comprises an optional metallic material and includes a plurality of thin openings (3). In order to improve the layer-settling process, the settling structure comprises a thin plate (2) or a film in which openings (3) are formed during the formation of expanded metal, wherein said openings are further bent so as to obtain slots of a predetermined width (B). The expanded metal then recovers its initial shape under a mechanical action so as to form slots with a given width. The openings (3) have a slightly conical shape which is widening in the flow direction.

    Abstract: An article, such as a filter or film, has a treated laminate with an expanded PTFE membrane and a porous support scrim. The treated laminate is formed by contacting a laminate having an expanded PTFE membrane and a porous support scrim with an oleophobic treatment agent dissolved in an organic solvent. The oleophobic treatment agent is deposited onto the expanded PTFE membrane and porous support scrim as the organic solvent is removed. The oleophobic treatment agent is typically a fluoropolymer. The article can be used, for example, as a filter over a port in a housing of an electronics or other device.
