About

PTFE Enhanced Perfluorosulfonic Acid Ion Exchange Membrane N-51

Perfluorosulfonic acid ion exchange membrane, also known as perfluorosulfonic acid proton exchange membrane and cation exchange membrane, is a solid polymer electrolyte, a strong acid type ion exchange membrane, with good chemical and thermal stability, low voltage, and low membrane resistance. High conductivity, good hydrophilicity, high water content of the membrane, high mechanical strength, etc.,It can be used under harsh conditions such as strong acid, strong alkali, strong oxidant medium and high temperature.
This membranes N-51 are reinforced membranes based on chemically stable perfluorosulfonic acid (PFSA) copolymer. Incorporation of the PTFE mesh reinforcement improves the mechanical property of the composite membrane and allows the membrane to restrict its swelling. The membranes show significant improvements in features such as better resistance to chemical attack and longer operating durability under electrolyzing cell conditions.

Application:

The Ion-Exchange Membrane N-51 are widely used in chlor-alkali industries, electro-dialysis, recovery of copper from etching solutions, synthesis for gold potassium cyanide, chlorine dioxide, and electrochemical reaction for amino acid. The membrane performs as a conducting separator and solid electrolyte in a variety of electrochemical cells which require the membrane to selectively transport cations across the cell junction.
The membranes N-51 are reinforced by PTFE fabric, and used in the chlor-alkali industry for the production of NaOH 32% and KOH.

Order and Packaging Information:

The membrane for cut pieces will depend on the size and quantity of the customer order requirements. The membrane pieces or rolls can be cut to non-standard sizes, please contact our sales staff for details and availability.
SY13P membranes are supplied in pre-expanded wet form. They provide an easy-to-use membrane while offering improved resistance to membrane damage from handling. During assembly, dry out can occur, which must be avoided to prevent slight shrinkage of the membrane. Do not unseal the package until ready to transfer to the water bath. Also, keep any unused membranes in the original container, packed as received, or store them wet in water. Prior to the installation of the membrane, the membrane should be removed from the package and put in a water bath at the required pH. During installation, keep the membranes wet by spraying with water every few minutes.
