Abstract

Communications cable is provided for use in downhole wells wherein the cable will be exposed to a temperature of at least 280° C., the cable including as a component thereof a composition comprising melt-fabricable tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer and melt flowable polytetrafluoroethylene, said polytetrafluoroethylene by itself having no tensile property and being present in said composition in an amount effective to enable the component to withstand this temperature, with the high temperature exposure of the cable component being effective to thermally transform the composition in the solid state, thereby obtaining epitaxial co-crystallization.
