Product Description

We supply both anion and cation exchange membrane for electrocoat process and water treatment industries. Nowadays, anion exchange membrane is popular used for most of CED systems, which is approved by PPG, Dupont, Valspar, Kansai and many other electrocoat paint systems. Moreover, our ion exchange membranes can be used in electro deionization systems for the production of ultra-pure water. We have three types of anion exchange membrane sheet, please see below table for the detail:
