    摘要: The present invention relates to a composition consisting of a fluoropolymer and a white inorganic filler, said composition being intended for the manufacture of monolayer films opaque to visible tight and to UV radiation, useable in particular in the field of photovoltaic cells. The polymeric composition consists of a fluoropolymer and zinc oxide (ZnO), said filler being present in said composition in a weight proportion of 20 to 40%, preferably 20 to 35%. The use of this filler serves on the one hand to avoid the addition of acrylic polymers to the fluoropolymer, and on the other hand, to use processing temperatures that are compatible with the manufacture of a monolayer film by extrusion blow moulding, that is, a temperature of about 220 to 260° C., thereby serving to prevent the degradation of the fluoropolymer.

    摘要: The invention relates to a multilayer tube comprising (in the order starting from the inside to the outside of the tube) layers arranged one on top of the other: an optional layer L1 comprising at least one fluorinated polymer, preferably a PVDF; a layer L2 comprising at least one functionalized PVDF, obtained by radiation grafting of at least one unsaturated polar monomer onto a PVDF; an optional layer L3 of an adhesive binder; a layer L4 comprising at least one polyolefin optionally mixed with at least one functionalized polyolefin; an optional barrier layer L5; an optional layer L6 comprising at least polyolefin, optionally in a mixture with at least one functionalized polyolefin; characterized in that the PVDF onto which the unsaturated polar monomer is grafted is a VDF copolymer whose weight content is at least 50%, preferably at least 75% and at least one monomer copolymerisable with the VDF, having the following characteristics: a crystallization temperature Tc (measured by DSC as per the ISO Standard 11357-3) ranging from 50 to 120°C, preferably from 85 to 110°C; a constraint to the y threshold ranging from 10 to 40 MPa, preferably from 10 to 30 MPa; a viscosity v in the molten state (measured with a capillary rheometer at 230°C at 100 s-1) ranging from 100 to 1,500 Pa s, preferably from 400 to 1200 Pa s.
