  • Patent number: 9786803
    Abstract: The invention relates to a multi-layer weatherable film structure having an outer layer of a highly weatherable film, a layer having a high thermal deformation temperature, an optional tie layer, and a thin layer of polyolefin or polyamide. The highly weatherable film layer preferably is polyvinylidene fluoride. The polyolefin or polyamide layer is less than 500 microns in thickness, and preferably the whole film structure is less than 750 microns thick. The polyolefinjpolyamide side of the film structure can easily be adhered to many different substances—especially polyolefins and polyamides. This film can be used to provide a highly weatherable protective layer a substrate. One useful application for the film is in a photovoltaic module to protect the back side of the module from weathering and abrasion. The multi-layer film structure can be adhered to a typical polyolefin-based encapsulant layer and used as a backsheet encapsulant in a photovoltaic module.

  • Patent number: 8501862
    Abstract: The invention relates to an extrusion agent comprising: at least one heterogeneous PVDF (A), in other words a copolymer of VDF and at least one comonomer of VDF, comprising by weight at least 50%, advantageously at least 75%, of VDF which has a melting point Tm (expressed in ° C.)>172-549 m, preferably >1.1×(172-549 m), where m denotes the overall molar percentage of comonomer(s); and at least one interface agent (B), which are optionally diluted in a polyolefin (C). The heterogeneous PVDF preferably has a Tm of between 160 and 172° C. Advantageously it is also a VDF-HFP copolymer containing, by weight, from 88% to 92% of VDF and from 8% to 12% of HFP. The extrusion agent is used to reduce or eliminate the surface defects which arise during the extrusion of a thermoplastic resin (D).

  • Publication number: 20130112268
    Abstract: 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.
