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:
The present invention relates to plenum cables jacketed with a composition comprising perfluoropolymer, inorganic char-forming agent, and hydrocarbon polymer, which passes the NFPA-255 burn test.

The present invention relates to plenum cables jacketed with a composition comprising perfluoropolymer, inorganic char-forming agent, and fluoropolymer additive, which composition passes the NFPA-255 burn test.
摘要:
The present invention relates to jacketed cable especially useful for plenum enclosures of buildings, the jacket of the cable comprising perfluoropolymer, such as tetrafluoroethylene/hexafluoropropylene copolymer, and inorganic char-forming agent, and preferably an additional ingredient, hydrocarbon polymer, the cable passing the NFPA-255 burn test.
