The F-10100 is a fluorinated cation-exchange membrane designed for electrochemical processes that require high oxidative stability. It features a non-reinforced design with a thickness of 100 μm, offering low resistance, high mechanical stability, high selectivity, and excellent chemical and oxidative stability. This membrane is suitable for applications such as water electrolysis and redox-flow batteries. It is supplied in a dry, non-activated form on a transparent, slightly brown PET backing foil and requires careful handling to avoid damage. The membrane can be pretreated in an aqueous 10 wt% H₂SO₄ solution at 70–90 °C for at least 6 hours to achieve optimal performance. It is important to note that the product is not certified for drinking water applications and requires proper handling and pretreatment to ensure its effectiveness.
