摘要:
Polyamide coating compositions that demonstrate strength and toughness, flame and corrosion resistance and resistance to hydrolysis and thermal degradation at coating thicknesses of less than or equal to 0.25 mm or 0.15 mm are provided. Such coating compositions are extremely useful for coating wires or cables that are housed in automotive electrical harnesses.

摘要:
Zero halogen polyolefin compositions exhibit low smoke emission, low corrosivity, low toxicity, and low heat release properties, as well as flame resistance and char formation, while simultaneously maintaining favorable electrical insulation properties. Such compositions are especially useful for coating wires and conductors employed in high-speed speed telecommunication data transmission cables.
摘要:
The present invention relates to the extrusion of a composition comprising tetrafluoroethylene/hexafluoropropylene copolymer, 10-60 wt % inorganic particulate filler, and hydrocarbon polymer for dispersing the filler in the copolymer, preferably 0.1 to 5 wt % hydrocarbon polymer, at low temperatures, e.g. up to 650° F. (343° C.).
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.

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.
