Aquivion PW79S About

Brand: Solvay Specialty Polymers USA

Product Code: 72800020

AquivionPW79S coarse, acid powder is based on the short-side-chain (SSC) copolymer ofTetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE)CF2=CF-O-(CF2)2-SO2F produced by Solvay. The resulting perfluoropolymer'sfunctional groups are in their sulfonic acid form, SO3H. Aquivion PW79S ischemically-stabilized (denoted by the S-suffix). Chemicalstabilization process is also known as end group conversion in which a largeamount of polymer end groups are converted to their inert "CF3"configuration, and as such provides excellent lifetime. Chemically stabilizedPFSA powders would exhibit substantially lower fluoride ion release compared tothe non-stabilized polymer a sign of improved chemicaldurability.

AquivionPW79S is characterized by a low equivalent weight (770 to 810 g/eq) and a highionic exchange capacity. The total acid capacity for Aquivion PW79S is1.23 to 1.30 meq/g. It can be used as is under conditions whereconventional exchange resins have shown insufficient chemical resistance.

Dueto its superacid functionality with many active groups, it can be used eitherdirectly or as an ingredient of composite structures active as a heterogeneouscatalyst. This encompasses a wide range of organic syntheses and respectivereaction mechanisms. It is insoluble in water, acid or bases and in mostsolvents unless extreme conditions are applied.

AquivionPW79S can be dissolved in some organic solvents to produce ion exchage capacitymembrane. Proper organic solvents are dipolar aprotic such as N-ethyl-2-pyrrolidone(NEP) and dimethyl sulfoxide. To facilitate the dissolution, slightly increasethe temperature to 50-60C.

Key Advantages of Aquivion's Short SideChain Based PFSA Powders:

Very highconcentration of functional groups for strong proton (or Na+, K+, Li+, etc.)conductivity

High softening point for high temperature operation well above 80 C

Strong water retention for better fuel cell operation at low-humidityconditions

Comparison of Short Side Chain and LongSide Chain PFSA Powders:

Aquivion PFSAs short side chain powder products makeit possible to achieve either better mechanical properties at the same IEC(ion-exchange capacity) or a higher IEC at the same mechanical properties thanlong side chain (LSC) based PFSA powder.
