Kel-F® (PolyChloroTriFluoroEthylene)
Chemicals which interact with Kel-F® (PCTFE) polymer are not pH dependent; rather, interaction is more determined by other physical properties of the chemical(s) in question. In general, only THF and a few halogenated solvents will react with this polymer. DMSO.
