Product Introduction

Product brief introduction: CM-PTFE type perfluorinated sulfonic acid reinforced membrane is formed by solution casting film method. Due to the addition of high-strength polytetrafluoroethylene mesh as a support layer and the combination of perfluorinated sulfonic acid resin with appropriate molecular weight and ion exchange capacity, the CM-PTFE type of perfluorinated sulfonic acid reinforced membrane is compared with the ordinary CM-10N series of perfluorinated sulfonic acid membranes, the capacity loss caused by the mutual channeling of the positive and negative solutions caused by the swelling of the membrane is effectively reduced, and the chemical resistance and durability of the membrane itself are greatly improved. Widely used in: chlor-alkali industry, Electrolytic Water Hydrogen, chlorine dioxide generator, amino acid refining, gold salt preparation, etching solution recovery copper and other fields.
