Perfluoroionic SY287 Ion-exchange membranes 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.

Applications:
SY287 membrane is produced with sacrificial core material, suitable for 30-32% caustic soda production.
SY287 membrane is suitable for running bars with high current density.
SY287 membrane has higher tolerance to salt water impurities
