MS Oleophobic PTFE Membrane for Venting

The hydrophobic and oleophobic PTFE membrane has strong hydrophobic and oleophobic performance, which can prevent the penetration of pollutants with low surface tension, including detergent, oil and chemicals. The oleophobic test is conducted according to The American Association of Textile Chemists and Colorists (AATCC)118-1989 standard. The test method is to drop the liquid with known surface tension on the surface of the membrane material and observe the wetting condition. This process is the process of liquid entering the membrane structure. The oleophobic grade is the liquid that cannot wet the minimum surface tension of the membrane material.
