PROTECTIVE FILM FOR A SOLAR CELL MODULE

摘要

The invention relates to a protective film for a solar cell module, to a process for manufacturing said protective film and to a solar cell module comprising said protecting film. The protective film comprises at least one layer comprising a perf luoropolyether (PFPE) polymer [polymer (F)], said polymer being obtainable by cross-linking a composition [composition (C) ] comprising : a) at least one functional perfluoropolyether compound [compound (E) ], said compound (E) comprising a (per) fluoropolyoscyalkylene chain [chain (Rf)], and at least one unsaturated moiety, said compound (E) being present in an amount included in the range of 10 % to 95 % wt with respect to composition (C); b) at least one nonfuorinated compound [compound (M) ] having at least one unsaturated moiety, provided that said nonf luorinated compound (M) has at least two unsaturated moieties if compound (E) has one unsaturated moiety; and c) at least one crosslinking initiator.
