• PFSA-PW-1890 Resin Powder (Low EW Grade)

PFSA-PW-1890 resin powder is a coarse, acid powder that is based on the long side chain perfluorosulfonic acid (PFSA) polymer chemistry.  Functional groups are in their sulfonic acid form, SO3H. This is a chemically-stabilized resin powder.  Chemical stabilization process is also known as end group conversion in which a large amount of polymer end groups are converted to their inert "CF3" configuration, and as such provides excellent lifetime. Chemically stabilized PFSA powders would exhibit substantially lower fluoride ion release compared to the non-stabilized polymer – a sign of improved chemical durability.  

PFSA-PW-1890 resin powder is considered to be low equivalent (EW) weight compared to other resin products in the market and EW value for this product is calculated to be in the range of EW 800-900. Low EW resin powders usually provide high ionic exchange capacity because of the higher number of sulfonic acid sites per unit gram of the product compared to higher EW resin powders. It can be used as is under conditions where conventional exchange resins have shown insufficient chemical resistance.

Due to its superacid functionality with many active groups, it can be used either directly or as an ingredient in the relevant applications (such as solid acid in organic synthesis, etc.). This encompasses a wide range of organic syntheses and respective reaction mechanisms. It is insoluble in water, acid or bases and in most solvents unless extreme conditions are applied.  

This product can be dissolved in various organic solvents or aqueous solvents to manufacture ionomers or dispersions. The dissolution process requires the end user to have specialty reactors that are suitable for this material and the necessary precautions in place from a safety aspect.  Fuel Cell Store strongly recommends the customers to review the existing literature in the public domain for how to dissolve PFSA resin powders safely.
