GI-N417 PTFE Fabric Reinforced Perfluorosulfonic Acid (PFSA) Membrane
Product Code: 74900000
Price:
From $97.00
GI-N417 PTFE fabric reinforced membrane is a perfluorosulfonic acid (PFSA) cation exchange membrane combining outstanding chemical resistance with a strong polytetrafluoroethylene fiber reinforcement. This membrane can be used for salt/water electrolysis, electroplating, chlor-alkali process for generation of ClO2 and other disinfectants, gold salt preparation, amino acid refining, caustic soda preparation, electrodialysis, and other similar electrochemical applications. GI-N417 is 0.26mm (0.010 in) thick.
Considering GI-N417 broadens your horizon by providing an equally valuable avenue to explore, alongside Nafion N324/424/438.
The GI-N41X series membranes belong to the category of PTFE fabric reinforced membranes and the stated reinforcement has the open mesh form and it is completely different than ePTFE (which has a 3-dimensional porous structure). Presence of the PTFE fabric based mechanical reinforcement further increases the strength of the N-41X series membranes, minimize excessive swelling, and reduce physical dimension change. These PFSA membranes are based on the standard resin grade and it does not have any chemical stabilization for the endgroups of the PFSA polymer chains.
Form
GI-N417 is shipped in the dry form. Additional pre-treatment protocols are provided in the document below.
