    摘要： The present invention relates to multilayer films made of fluoro polymers, which have properties that make them suitable for use in the agricultural field, especially as greenhouse covering films. According to a first aspect, the invention relates to multilayer fluorinated films comprising at least three layers, including a layer A made of a first vinylidene fluoride copolymer with a crystallization temperature TcA, and a layer B made of a second vinylidene fluoride copolymer with a crystallization temperature TcB, TcA being greater than TcB, layers A and B being alternating, layer A being placed to the exterior and layer B between two layers A. Another subject of the invention relates to the use of the film according to the invention as an agricultural covering material, especially as a greenhouse covering.

    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.

    摘要翻译： 本发明涉及一种由氟聚合物和白色无机填料组成的组合物，所述组合物旨在用于制造对于可见的紧密和紫外线辐射不透明的单层膜，特别是在光伏电池领域中。 聚合物组合物由氟聚合物和氧化锌（ZnO）组成，所述填料以20-40％，优选20-35％的重量比存在于所述组合物中。 使用这种填料一方面是为了避免向含氟聚合物中加入丙烯酸聚合物，另一方面，使用通过挤出吹塑成型制备单层膜的加工温度，即， 温度为约220至260℃，从而用于防止含氟聚合物的降解。
