COAXIAL CABLE WITH FOAMED INSULATION

摘要

The present invention is directed to a coaxial cable comprising (a) an inner conductor, (b) an outer conductor, and (c) a foamed insulation, surrounding the inner conductor. The foamed insulation is prepared from an insulation composition comprising a foamable polymer, a foaming agent, and a particulate, non-halogenated, non~heterocyclic polyolefinic nucleating agent. The invention is also related to methods and compositions for making the foamed insulation.
