Product Description

Cosposite PEM,formed by using unique tape casting process with appropriate molecular weight and ion exchange capacity of perfluorosulfonic acid resin,and uniform thickness, is widely used in electrolytic chlorine dioxide generator, etching solution recovery copper, gold salt preparation, amino acid refining, caustic soda preparation, electrodialysis and other electrolytic industries.

The strength,moisture tetention and vanadium resistance of ion exchange membranes were improved by introducing special materials into the tape casting processc

1  Measurements taken with membrane conditioned to 23ºC,50% RH.
2  Conductivity measurements a 23 'C, 100% RH.
3  A basetitration procedure measures the equivalents of sulfonic acid in the polymer, and uses the measurement to calculate the acid capacity or equivalent we ight of the membrane.
4  Dissolved Hydrogen Concentration was performed using a Hydrogen rich water test pen (ENH 1000 Portable Dissolved hydrogen Meter), which was based on the principle of oxidation reduction potential in the solution to calculate the dissolved hydrogen concentration.
5  Water content of membrane conditioned to 23ºC and 50% RH (dry weight basis).
6   Water uptake from dry membrane to conditioned in water at 100 'C for 1 hour(dryweight basis).
