Patent ID: 7387750

Claim:
A melt-processable conductive fluorothermoplastic composition comprising: A) a major amount of at least one melt-processable, thermoplastic fluoropolymer having its interpolymerized units derived from (i) at least 50 weight percent (wt %) of tetrafluoroethylene (TFE), (ii) one or more ethylenically-unsaturated monomers represented by the formula (a) CH 2 ═CR 2 , and, optionally, one or more ethylenically-unsaturated monomers represented by the formula (b) CF 2 ═CF—O—R f ′, and (c) CF 2 ═CFR f wherein R f is a perfluoroalkyl of 1 to 8 carbon atoms, R f ′ is R f or a perfluoroalkoxy of 1 to 8 carbon atoms, and R is selected from H, F, Cl, or an aliphatic group having from 1 to 8 carbon atoms which may have F or Cl substituents, provided that the thermoplastic fluoropolymer has less than 5 wt % of its interpolymerized units derived from vinylidene fluoride (VDF); B) from about 0.1 to about 4 weight percent of a hydrocarbon polymer having a weight average molecular weight of a least about 45,000; and C) from about 1 to about 20 weight percent of conductive filler.
