Abstract
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.
Claims16
A composition capable of forming a melt-fabricated article that passes the NFPA-255 burn test, comprising melt-fabricable perfluoropolymer, about 10-60 wt % char-forming inorganic agent, and about 0.1 to 5 wt % fluoropolymer additive to total 100 wt % based on the combined weight of said perfluoropolymer, agent and fluoropolymer additive, said fluoropolymer additive acting to disperse said agent in said perfluoropolymer during melt-blending.
