  • Highly filled unsaturated fluoropolymer compositions for cables
    Patent number: 7625974
    Abstract: A non-dripping, flame retardant, fluoropolymeric composition comprising: (a) a fluoropolymeric base polymer; (b) at least one char forming agent; and (c) a compatibilizer agent. The fluoropolymeric base polymer is preferably selected from the group consisting of PVDF (polyvinylidene fluoride), ECTFE, poly-ethylene chlorotrifluoroethylene, and ETFE poly-ethylene tetrafluoroethylene. Such compositions are especially useful for appliance wire, aerospace/military wire, cable raceways, blown fiber tubes, fire alarm cables, circuit integrity cables, fiber optic distribution cables & breakout components, heat tracing cable jacket, stage lighting cable, industrial cable, shipboard cable (military & passenger), shielded cable jackets.
