Perfluorosulfonic acid ion exchange membrane
Perfluorosulfonic acid ion exchange membrane
Perfluorosulfonic acid proton exchange membrane
The perfluorinated cation exchange membranes are non-reinforced films based on chemically stabilized perfluorosulfonic acid, we produce the cation exchange membranes with the new casting method, the casting process can be combined with doping technology,we add new fluororesin mixing formula with good vanadium resistance in the casting process, the Ion-Exchange Membrane has high tensile strength, isotropic, high electrical conductivity, good chemical properties, and so on.

Applications:
Our Perfluorinated Ion-Exchange Membrane is particularly suitable for use as a solid electrolyte membrane in Proton Exchange Membrane (PEM) fuel cells, water electrolyzers,vanadium cells, electrolytic cells, electrodialysis, electrochemical sensors, and so on.The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells that require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable.
Packing:
Our Perfluorinated Ion-Exchange Membrane has sheet and continuous roll:
Sheet material standard size:600mm*600mm;800mm*800mm;1000mm*1000mm
Continuous Roll: 800mm width and 680mm with continuous roll
We can also provide special customized size according to your requirement.
Standard packing is packaging the PIEM in plastic drum or bucket.
