General description【一般描述】
Aquivion® PFSA dispersions are based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) CF2=CF2-O-(CF2)2-SO2F industrially produced by Solvay Specialty Polymers. The resulting perfluoropolymer′s functional groups are in their sulfonic acid form, SO3H.
Application【应用】
Aquivion® D72-25BS can be used as a formulation additive for the production of polymer electrolyte fuel cell electrodes, manufacturing or repairing of cation-exchange membranes, surface coatings of PTFE membranes to improve their wetting behavior or for the development of superacid catalysts. The addition of further film-forming and/or other volatile or non-volatile chemicals is necessary to impart the desired processing and end-product characteristics.
Other Notes【其他说明】
Features & Benefits:
Aquivion® D72-25BS is delivered as a colloidal dispersion in highly pure deionized water. It contains the perfluoropolymer′s sulfonic acid form (R-SO3H) of equivalent weight (EW) 720g/mole SO3H at very high solid content of 25% by weight which allows a large variety of subsequent formulations without additional pre-concentration steps.
D72-25BS contains "chemically stabilized" perfluoropolymer in which a large amount of polymer end groups are converted to their inert "CF3" configuration.
Hydrophilicity, swelling and water retention at dry state are more pronounced than for D79-25BS, D83-24B or D98-25BS.
