摘要： A method of potting porous hollow fiber membranes made from a thermoplastic perfluorinated resin with a polymer of a similar chemical construction is disclosed. This allows for the formation of an all perfluorinated thermoplastic hollow fiber membrane device. Thermoplastic perfluorinated resins include poly(TFE-co-PFAVE), commonly referred to as PFA, MFA or FEP resins and blends thereof. The method involves the application of a potting resin selected from one or more thermoplastic perfluorinated resins which have a peak melting point below that of the fiber. After one or both ends of the bundle of fibers has been potted, they are subjected to a heating treatment which causes the potting compound to melt such that the resin flows between the fibers to remove any gaps or voids which may be present.

摘要： High flux porous hollow fiber membranes are produced from perfluorinated thermoplastic polymers by extruding a heated solution of the polymer having a lower critical solution temperature directly into a cooling bath to form the porous membrane by liquid-liquid phase separation. Extrusion can be conducted either vertically or horizontally.

摘要： A filtration cartridge having a housing with an inlet and an outlet and a filtration membrane contained within the housing and located between the inlet and the outlet is described. The membrane is sealed in such a manner that all fluid must flow through the membrane between entering the inlet and leaving the outlet of the housing. The entire cartridge, housing, membrane and any other components are all formed of one or more perfluorinated thermoplastic resins. These resins preferably are PFA, MFA, FEP and blends thereof. The membrane may be in the form of hollow fibers, wound fibers such as in a depth filter, or a flat sheet which may be formed into various configurations such as spiral filters, pleated filters, spiral pleated filters, disks and the like. These cartridges provide an inert, high temperature and acid/oxidative chemical resistant filter having properties similar to that of PTFE resins.

摘要： Hollow fiber membranes having a skinned surface on one diameter, and a porous surface on the opposite diameter are produced from perfluorinated thermoplastic polymers by extruding a heated solution of the polymer having a lower critical solution temperature directly into a cooling bath to form the porous membrane by liquid-liquid phase separation. Extrusion can be conducted either vertically or horizontally. The hollow fiber membranes are useful as ultrafiltration membranes and as membrane contactors.
