  • Electrically conductive polymer composition
    Patent number: 5298194
    Abstract: A polymer composition comprises a solid fusible particulate polymer material and a quantity of metal particles that have been blended with the particles of polymer material to render the composition electrically conductive. The composition may be consolidated by subjecting the particulate blend to heat and/or pressure. The electrically conductive polymer composition may be used to connect the electrically conductive screen (7) of a dimensionally recoverable article (6) to the electrically conductive shield (4) of a cable (1).
