PTFE Fluoropolymer Filters for High-Purity/Aggressive environments
Flontex PTFE membranes are used extensively in pharmaceutical, laboratory, medical & semi-conductor processing applications where ultra pure or highly aggressive fluids & gases need to be filtered using inert, non-clogging filter media.
Flontex PTFE membranes are self supporting so backing liners are not required. Being naturally hydrophobic Flontex is an excellent venting material & due to its non-stick quality, Flontex exhibits unrivalled filter cake release properties. As standard, Flontex PTFE membranes are supplied as punched discs, however, semi-finished material in roll or sheet form is available on request.
