Generic Teflon Fabric Reinforced N324 N424 N438 Proton/Cation Exchange Membrane (N424_30cm*30cm)

Please Note: The side marked CATH must be installed facing the cathode, otherwise, the membranes will be irreversibly damaged in use. If your membrane is not marked simply feel/look at both sides of the membrane, the smoother/glossier side will be the cathode side.

• N324 is a perfluorosulfonic acid cation exchange membrane combining outstanding chemical resistance with a strong polytetrafluoroethylene fiber reinforcement. It is recommended for use in chloroalkali production and a variety of electrolytic processes. N324 is 0.28mm thick.
• N424 is a perfluorosulfonic acid cation exchange membrane combining outstanding chemical resistance with a strong polytetrafluoroethylene fiber reinforcement. It is recommended for use in chloroalkali production and a variety of electrolytic processes. N424 is 0.38mm thick.
• N438 is a new product in the 400 series family. This membrane represents the state-of-the art in fabric reinforced cation exchange membranes. It has a new PTFE mono-filament reinforcement with high strength but N424. N438's edge leakage is reduced and expansion characteristics are more uniform than N424.
• N324 N424 N438 is shipped in the "DRY" H+ form. "DRY" H+ membranes require simple pre-treatment in alkaline water.
