PTFE Membranes

FLONTEX™ 100

About PTFE Membranes

PTFE Filter Membranes (FLONTEX™ 100) 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.

PTFE 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. FLONTEX™ 100 Filter Discs are supplied in packs of 50. Paper discs are placed between PTFE membranes to ensure cleanliness.
