About

PTFE Reinforced Perfluorosulfonic Acid Ion Exchange Membrane N-41 for Chlor-Alkali Industry

Phosphate

This membranes N-41 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-41 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-41 are reinforced by PTFE fabric, and used in the chlor-alkali industry for the production of NaOH 32% and KOH.
