Professional Perfluorinated Ion-Exchange Membrane(PIEM) and Homogeneous Ion-Exchange Membrane manufacturer in China


For production of chlorine and caustic by electrolysis, we develop SY287 Ion-exchange membranes which 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. SY287 Ion-exchange membranes 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 electrolysing cell conditions.

Excluding China, there are three suppliers for chlor-alkali ion-exchange membrane all over the world, we compared the properties with the three suppliers as follows:(Reference Standard):
