Abstract
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.
Claims20
A composition consisting essentially of perfluoropolymer, about 10-60 wt % char-forming inorganic agent, and about 0.1 to 5 wt % hydrocarbon polymer that is thermally stable at the melting temperature of said perfluoropolymer, to total 100 wt % based on the combined weight of said perfluoropolymer, agent and hydrocarbon polymer.
A composition comprising perfluoropolymer, about 10-60wt% char-forming inorganic agent, and about 0.1 to 5 wt% hydrocarbon polymer that is thermally stable at the melting temperature of said perfluoropolymer, to total 100 wt% based on the combined weight of said perfluoropolymer, agent and hydrocarbon polymer, wherein said hydrocarbon polymer is thermoplastic elastomer.
A composition comprising perfluoropolymer, about 10-60 wt% char-forming inorganic agent, and about 0.1 to 5 wt% hydrocarbon polymer that is thermally stable at the melting temperature of said perfluoropolymer, to total 100 wt% based on the combined weight of said perfluoropolymer, agent and hydrocarbon polymer, wherein said composition is free of added antioxidant.
