ABSTRACT:
A communications cable is provided having at least one elongate electrical conductor surrounded by a layer of insulating material, said layer including a chemically blown fluorinated polymer having a melting point of greater than about 480.degree. F. The elongate electrical conductors may be provided as at least one pair of twisted wires, each wire thereof surrounded by a layer of insulating material including the chemically blown fluorinated polymer. The fluorinated polymer is preferably a high melting fluorinated polymer and is chemically blown by a blowing agent such as the barium salt of 5-phenyltetrazole. The communications cable includes insulated wires which possess a layer of foamed fluorinated polymer insulating material having uniform thickness and electrical properties along the length of the wire. The fluorinated polymer can be applied on the conductor in a relatively thin layer which minimizes the amount of fluorinated polymer material used to insulate the individual conductors.
