  • 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.

  • Patent number: 6797760
    Abstract: 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.

  • Patent number: 5670748
    Abstract: A flame retardant and smoke suppressant electrical insulation composition for an electrical conductor comprises an inner layer and an outer layer. The inner layer, which contacts and surrounds the conductor, comprises a foamed polymeric material selected from the group consisting of polyolefins and polyurethane. The outer layer, which contacts and surrounds the inner layer, comprises a halogenated polymeric material and at least one outer layer additive to render the outer layer flame retardant and smoke suppressant. A flame retardant and smoke suppressant insulated electrical conductor comprises a length of electrically conductive material surrounded by the insulation composition. A flame retardant and smoke suppressant jacketed electrical cable comprises a plurality of insulated electrical conductors.
