LAYERED ARTICLE OF FLUOROPOLYMER

摘要

PURPOSE: To provide a fluoropolymer laminated product containing no adhesive between its adjacent fluoropolymer layers, having film tearable interfacial bonding, not having the interfacial mixing of the fluoropolymer layers substantially and effectively thermoformed. CONSTITUTION: A laminated product comprises at least one polyvinyl fluoride layer and two or more polyvinyl fluoride layers can be also used. Other fluoropolymer capable of being used in the laminated product includes a homopolymer or copolymer of a monoethylenic unsaturated hydrocarbon monomer perfectly substd. by a fluorine atom or a combination of a fluorine atom and a chlorine atom. A first layer can be produced from a dispersion cast on the surface of a support. A second layer is molded to be united with the first layer at temp. lower than the m.p. of the first layer.
