F-10150-PTFE Cation Exchange Membrane

Built for demanding electrolysis and flow battery duty, the F-10150-PTFE is a PTFE-reinforced fluorinated cation exchange membrane engineered where mechanical durability under pressure and repeated thermal cycling matters as much as ionic performance. Its PTFE reinforcement layer raises burst resistance beyond 3 bar and tensile strength above 30 MPa while holding dimensional swelling under 6%, letting researchers run PEM water electrolysis and high-pressure flow cell trials without membrane failure. Supplied dry and non-activated, it can be run as-is or pre-activated in acid for immediate peak performance.

• Reinforced for Durability: PTFE reinforcement delivers a >300 MPa Young's modulus for demanding, high-pressure electrolysis setups.
• Dimensionally Stable: <6% swelling in water keeps gasket compression and cell alignment consistent over repeated cycling.
• Reliable Sealing: Burst test >3 bar confirms integrity under standard operating pressures.
• High Selectivity: >95% ion selectivity supports efficient PEM electrolysis and flow battery operation.
• Flexible Activation: Usable as delivered or pre-activated in dilute sulfuric acid for maximum initial conductivity.
• Cell-Ready Formats: Supplied as standard sheet stock or pre-cut for Redox Flow’s single-cell, X-Stack, and 3-compartment hardware.
