The Composite Ion Exchange Membrane for Water Treatment integrates a high-strength PTFE mesh as the supporting layer, combined with perfluorosulfonic acid resin optimized for molecular weight and ion exchange capacity (IEC). It exhibits outstanding chemical resistance and durability, making it ideal for water treatment applications. Engineered to handle harsh conditions, this membrane effectively serves in high-salinity wastewater treatment, electrodialysis (ED) processes, and other water purification scenarios, ensuring stable performance for efficient contaminant removal and ion management.

Measurement Notes
- Measurements taken with a membrane conditioned to 23℃, 50% RH
- Conductivity measurements at 23℃, 100% RH
- A base titration procedure measures the equivalent amount of sulfonic acid in the polymer of the membrane, and uses the measurement to calculate the acid capacity or equivalent weight of the membrane
- Water content of the membrane conditioned to 23℃ and 50% RH (dry weight basis)
- Water content of the membrane in water at 100℃ for 1 hour (dry weight basis)
- Tensile Test (Conditions: 23℃, 50% RH)
