CABLE INSULATION COMPOSITIONS WITH ENHANCED RHEOLOGY AND PROCESSABILITY

摘要

The present invention is a telecommunications cable comprising a plurality of electrical conductors, each conductor being surrounded by a layer of insulation comprising a coupled propylene polymer. It is preferable that the propylene polymer be an impact modified propylene polymer, more preferably an impact propylene polymer. The primary advantages of the insulation composition are realized under high-speed extrusion conditions for thin-walled insulation application, including the advantages of smooth insulation surface, good dimensional uniformity, and relatively low extrusion head and die pressures.
