FLEXIBLE FILM BASED ON FLUORINATED POLYMER

摘要

The invention concerns a multilayer structure comprising: a PVDF-based film F1affixed to a PET or PEN sheet or a PVDF-based film F1 affixed to a PET or PEN sheet which is itself affixed to a PVDF-based film F2, The F1 and/or F2 films comprising (starting from the PET or PEN sheet): optionally a layer of composition B including 5 to 40 parts of at least one PVDF, 60 to 95 parts of at least one PMMA and 0 to 5 parts of at least one UV absorber, the total being 100 parts; a layer of composition A, including 50 to 100 parts of at least one PVDF, 0 to 50 parts of at least one PMMA, 0 to 30 parts of at least one mineral filler and 0 to 3 parts of at least one dispersant, the total being 100 parts; optionally a layer of composition C including 80 to 100 parts of at least one PVDF, 0 to 20 parts of at least one PMMA, 0 to 30 parts of at least one mineral filler and 0 to 3 parts of at least one dispersant, the total being 100 parts; such that and adhesive layer is interposed between the PET or PEN sheet and the F1 and/or F2 films; said adhesive layer being optional if the layer of composition B is present and not including any polyolefin functionalized by an unsaturated acid or anhydride or a homo-or copolymer including as monomer(s) acrylic acid, acrylates and alkyl acrylates optionally modified by an unsaturated acid or anhydride; such that the compositions A and/or B do not contain any acrylic elastomer particle nor any core-coat particle.
