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