Title
(EN) MULTILAYER FLUORINATED FILMS
(FR) FILMS FLUORES MULTICOUCHE
Abstract
(EN) The present invention relates to multilayer films made of fluoropolymers 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 3 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.
(FR) La présente invention concerne des films multicouche en polymères fluorés possédant des propriétés les rendant aptes à une utilisation dans le domaine agricole notamment comme films de couverture de serres. Selon un premier aspect, l'invention a trait à des films fluorés multicouche comprenant au moins 3 couches, dont une couche A en un premier copolymère de fluorure de vinylidène ayant une température de cristallisation TcA, et une couche B en un deuxième copolymère de fluorure de vinylidène ayant une température de cristallisation TcB, TcA étant supérieure à TcB, les couches A et B étant alternes, la couche A étant placée à l'extérieur et la couche B entre deux couches A. Un autre objet de l'invention concerne l'utilisation du film selon l'invention comme matériau de couverture agricole notamment comme couverture de serres.
