Perfluorinated Ion Membrane

Perfluorinated ion membrane consists of a hydrophobic skeleton and a hydrophilic sulfonic acid group. It is mass-produced through our patented “Dissolved Resin Casting” method. The product is characterized for its distinctive high acidic capacity, high conductivity, high power density, large tensile modulus, small linear expansion rate, isotropic nature, long operating life, and stable thermal, chemical and electrochemical performances.

The product is used as the electrolyte membrane in vanadium flow batteries, ion film electrolytic tanks and electrochemical sensors to separate the anode and cathode compartments.

Enhanced Perfluorinated Ion Membrane

Enhanced perfluorinated ion membrane consists of a hydrophobic skeleton and a hydrophilic sulfonic acid group. It employs the chemically stabilized PTFE mesh to increase the tensile strength. Its small linear expansion rate and long operating life are particularly suitable to be used in extreme environments.

The product is used as the electrolyte membrane to separate the anode and cathode compartments for the recovery of precious metal (such as copper, gold), electrochemical synthesis and water treatment.
