    摘要: A non-dripping, flame retardant, fluoropolymeric insulative composition comprises: (a) a fluoropolymeric base polymer; and (b) a nanoclay additive. The preferred nanoclay additive is selected from the group consisting of synthetic silicate montmorillonites, natural layered silicate montmorillonites and a layered alumna-silicate. Such compositions are especially useful for coating wires and conductors employed in high-speed speed telecommunication data transmission cables. A method for preparing an exfoliated thermoplastic elastomer blend of a fluoropolymer and a nanocomposite comprising dynamically mixing said fluoropolymer and said nanocomposite in a ratio of from about 99:1 to about 50:50 parts by weight, respectively.

    摘要: 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.
