Abstract

A method for producing a cable by covering with polytetrafluoroethylene and extrusion molding with a perfluoroalkoxy compound, including: covering an outer surface of a conductor with an insulation layer; and extrusion molding a skin layer on an outer surface of the insulation layer to form a cable. The insulation layer and the skin layer are made of polytetrafluoroethylene and a perfluoroalkoxy compound, respectively. The perfluoroalkoxy compound and polytetrafluoroethylene both have high temperature resistance, good electronic signal transmitting performance, and non-bonding surface, etc., and the perfluoroalkoxy compound has a Shore hardness of 60 to 70D, which can impart the skin layer a certain hardness, and is suitable for being extrusion molded on the outer surface of the insulation layer made of polytetrafluoroethylene, so as to support the insulation layer and prevent the insulation layer from being deformed. Therefore, the perfluoroalkoxy compound is the most suitable material for the skin layer.
