产品说明

一般描述

Aquivion® D79-25BS-Li is a dispersion 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 lithium sulfonate form, SO3Li. Aquivion® D79-25BS-Li is delivered as a colloidal dispersion in highly pure deionized water. It contains the perfluoropolymer′s neutral lithium salt form (R-SO3Li) of low equivalent weight (EW) 790 g/mole SO3H at very high solid content of 25 % by weight which allows a large variety of subsequent formulations without additional pre-concentration steps. D79-25BS-Li contains "chemically stabilized" perfluoropolymer in which a large amount of polymer end groups are converted to their inert "CF3" configuration.

应用

Once formulated with solvents Aquivion® D79-25BS-Li can be used for the preparation of cast films or membranes, of coatings on various substrates. Formulations with volatile and non-volatile additives to make components for electrochemical devices are another possible way of using D79-25BS-Li.
