Good afternoon. Similar to DMF, DMAC has strong solubility in many organic compounds, but as far as I know, it is not a good solvent for perfluororubber and PTFE. Other fluorinated synthetic rubbers, such as FKM and FVMQ, are also insoluble in DMAC and can only be dissolved by a small amount of fluorine-containing solvents and liquid ammonia. Please refer to. Both perfluororubber and polytetrafluoroethylene belong to organic compounds.
