We are located in a beautiful seaside city-Weifang, Shandong province in China. The city is conveniently connected by all kinds of transportation facilities: ocean shipping, highway, and airfreight.We supply the ion-exchange resin, chlor-alkali membrane, ion-exchange membranes, (including the anion exchange membrane, cation exchange membrane and bipolar membrane), membrane stack, electrolyzer for the production of hydrogen, electrodialyzer and bipolar electrodialyzer which converts the salt to base and acid.We have the Ion-Exchange Membrane(IEM) for the Production of Chlorine and Caustic by electrolysis which is environmentally friendly and has become the preferred method for chlorine and caustic production, many of our customers who produce Caustic Soda(NaOH) or Caustic Potassium(KOH) have used our Ion-Exchange Membrane for more than 3 years.Our Ion-Exchange Membrane(IEM) includes Perfluorinated Ion-Exchange Membrane(PIEM), PTFE Enhanced Perfluorinated IEM, and Homogeneous Ion-Exchange Membrane, the thickness is from 25-550 um with the width from 600mm-3000mm, special size customization is available according to the customer's requirement.Our Perfluorinated Ion-exchange Resin is widely used as the materials of ion exchange membrane, fuel cell ion membrane, ion exchange membrane for vanadium battery, ion membrane in Chlor-alkali industry, hollow fiber membrane, the super catalyst used in organic synthesis, ultra-stable ion exchanger, and so on.Our Ion-Exchange Membrane(IEM) is widely used for the production of chlorine and caustic by electrolysis and is used as solid electrolyte membranes in fuel cells, water electrolysis to produce the hydrogen,vanadium cells, electrolytic cells, electrodialysis, electrochemical sensors.Our bipolar electrodialyzer is used for converting the salt to acid and base, the produced base concentration is about 8% and the the produced acid concentration is about 6%.
