Description

Composite lon Exchange Membranefor Electrolysis or
Electroplating

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.

1.23°C,50% Rh24h. Measurement is taken with membrane conditioned to 23ºC,50%RH for 24h.
2.23°C,100% Rh. Conductivity measurement is conducted at 23ºC,100% RH.
3. A basetitration procedure measures the equivalents of sulfonic acid in the polymer, and uses the measurement to
calculate the acid capacity orequivalent weight ofthe pure polymer.
4.23 °C,50% Rh. Water content of membrane conditioned to 23ºC and 50% RH (dry weight basis).
