Hydrophobic membrane filters are necessary for applications where the membrane is used to retain liquid water while allowing gases to pass through. Hydrophobic PCTE membranes typically have insufficient water entry pressures for these applications and will allow liquid water to pass at pressures lower than required.

2007/5/1 · The chemical modified SPI/PTFE membrane was prepared by immersing the SPI/PTFE membrane into the 5% Nafion ® dispersion (Nafion ® R- resin, DuPont Fluoroproducts, USA). The coated membrane was dried in an oven at 60 °C for 12 h to remove the residual solvents and at 120 °C for 12 h to make the Nafion crystallization.

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.

1990/9/1 · Abstract. Investigations were carried out on the permeation of He, H 2, Ar, O 2 and N 2, in the range 26–60°C, and the separation at 20°C of a H 2 + N 2 gas mixture through a polytetrafluoroethylene (PTFE) membrane metallized in vacuum with a 1000 Å thick layer of palladium. In both experiments it was found that the thin layer of Pd acts
