FLONTEX™ 100 PTFE Filter Membrane

FLONTEX™ 100 PTFE Filter Membrane

 

(PolyTetraFluoroEthylene)

FLONTEX™100 PTFE Filter Membranes are used extensively in pharmaceutical, laboratory, medical & semi-conductor processing applications where ultra pure or highly aggressive liquids and gases need to be filtered using inert, non-clogging filter media.

FLONTEX™100 PTFE Filter Membranes are self-supporting so backing liners are not required. Being naturally hydrophobic FLONTEX™100 is an excellent venting material & due to its non-stick quality, exhibits unrivalled filter cake release properties. As standard, our PTFE membranes are supplied as punched discs, however, semi-finished material in roll or sheet form is available on request.
