Thermoplastic fluoropolymer compositions containing hydrogenated plasticizers

The present invention relates to thermoplastic fluoropolymer compositions for the plenum wire insulation and cable jacketing applications, that show a high time to ignition, a low smoke and heat release when put in contact with a heat source as for example in the Cone Calorimeter (see the ASTM E1354 test). Thermoplastic fluoropolymer compositions, flexible, without whitening, comprising: I) ETFE or ECTFE fluoropolymers modified with hydrogenated monomers; II) one or more hydrogenated plasticizers; III) one or more inorganic fire retardants; IV) optionally other ingredients such as fillers, smoke retarders, intumescent agents, pigments, lubricants, organic fire retardants and thermal stabilizers.
