Hydrophobic ePTFE Membrane

Expanded ePTFE membrane has strong chemical compatibility with pH 1-14, and is suitable for filtration of corrosive chemicals such as strong acids and bases. The ePTFE membrane features natural hydrophobic and high specific surface area. It can ensure air pass while blocking the flow of liquids, making it suitable for air filtration or water blocking and breathable applications. We also provide ePTFE membranes with oil repellent treatment. In addition to preventing water pass, it can effectively prevent liquids with low surface tension such as esters, alcohols, and oils from infiltrating and maintaining excellent air permeability. ePTFE oleophobic membrane meets the requirements of PFOA in the EU REACH regulation. ePTFE membrane can be adapted to various assembly methods such as backing adhesive, compression bonding, hot melt welding, ultrasonic welding, etc. It can be welded with materials such as ABS resin, polypropylene, PMMA and PC, etc.
