  • Fluid-impermeable areas on porous membrane filters and their application
    Patent number: 4969997
    Abstract: The invention relates to porous membrane filters, specifically mirco- and ultraporous membrane filters, which have fluid-impermeable areas as a result of a change of their structure on one side of the membrane to a film-like state (film-formation). These filters are, for example, very suitable for an assembly in filter cartridges according to the pouring method, because they still have on the side opposite to the filmed-up side a porous structure, which offers an ideal anchoring possibility for penetrating liquid resin.
