Perfluorosulfonic Acid Membrane N-515 220μm ATOMFAIR®

N-515 Perfluorosulfonic Acid Composite Ion Exchange Membrane for Water Treatment

Product Type: Composite ion exchange membrane

commercial grade product

Product Overview

N-515 is a 220 μm composite membrane with a filling weight of 290 g/m². It uses high-strength PTFE mesh as a supporting layer combined with perfluorosulfonic acid resin of optimized molecular weight and ion exchange capacity. This construction provides superb chemical resistance and durability. The membrane is widely used in high-salt wastewater treatment, electrodialysis, and other water treatment applications. The standard size is 1 square meter (1 m × 1 m).

The membrane is positioned for high-salt wastewater treatment, electrodialysis and related water treatment fields requiring chemical resistance and durability. Other sheet dimensions should be confirmed separately before quotation.

How does the PTFE mesh reinforcement in the N-515 membrane affect its dimensional stability under thermal cycling in electrodialysis?

The PTFE mesh support provides mechanical reinforcement that limits thickness change to ≤5% at 23°C and ≤8% at 100°C, and linear expansion to ≤2% at 23°C and ≤5% at 100°C. This ensures reliable dimensional stability during thermal cycling in electrodialysis processes, reducing risk of delamination or seal failure.

What are the conductivity and acid capacity constraints for using the N-515 membrane in high-salt wastewater treatment?

The N-515 membrane delivers a conductivity of ≥0.100 S/cm and an acid capacity of 1.00 ± 0.05 meq/g, enabling efficient ion transport in high-salt environments. These parameters are critical for maintaining consistent electrochemical performance in electrodialysis and related water treatment applications.

What handling and storage precautions are required for the N-515 perfluorosulfonic acid composite membrane to prevent damage before installation?

The membrane is supplied in standard packaging to ensure protection during transit, and custom sizes require email confirmation before quotation. Given its 220 μm thickness and PTFE mesh reinforcement, careful handling is needed to avoid creasing or tearing, and storage should be in a clean, dry environment to maintain the specified water content of 5.0 ± 3.0% and water uptake of 50.0 ± 5.0%.

Assessment

The N-515 composite ion exchange membrane uses PTFE-reinforced perfluorosulfonic acid resin to achieve tensile strength ≥40 MPa, elongation ≥100%, and conductivity ≥0.100 S/cm, making it suitable for high-salt wastewater electrodialysis, though dimensional changes up to 5% at 23°C and 8% at 100°C must be accounted for in system design.

Positive

PTFE-reinforced mechanical durability: High-strength PTFE mesh support provides tensile strength ≥40 MPa and elongation ≥100%, enabling reliable handling and operation in demanding electrodialysis and water treatment systems.
High ionic conductivity: Conductivity ≥0.100 S/cm ensures efficient ion transport, critical for maintaining low energy consumption in high-salt wastewater treatment processes.

Trade-offs

Dimensional sensitivity to temperature: Thickness change up to 5% at 23°C and 8% at 100°C, with linear expansion up to 2% at 23°C and 5% at 100°C, requires careful temperature management during operation and thermal cycling to maintain seal integrity.
Controlled water uptake variability: Water uptake of 50.0 ± 5.0% and water content of 5.0 ± 3.0% introduce minor performance variability in environments with fluctuating humidity, necessitating consistent hydration conditions for reproducible results.
