    Abstract: The invention pertains to a thermoplastic fluoropolymer composition comprising one or more polymer A comprising recurring units derived from ethylene and recurring units derived from halogenated monomers selected from chlorotrifluoroethylene (CTFE) and tetrafluoroethylene (TFE) and one or more polymer B comprising recurring units derived from ethylene, recurring units derived from halogenated monomers selected from CTFE and TFE, and recurring units derived from hexafluoroisobutylene (HFIB) and/or perfluoropropylvinylether (PPVE). The resulting composition allows to manufacture films having exceptional transparency and good mechanical properties which can be used for examples as architectural films.
