RESIN COMPOSITION AND HIGH-FREQUENCY COAXIAL CABLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin composition good in foamability and electrical properties. SOLUTION: The resin composition is a mixture obtained by adding 0.001 to 0.1 pt.wt. foaming nucleating agent to 100 pts.wt. mixture obtained by mixing 55 to 90 pts.wt. medium-density polyethylene having a density of 0.931 to 0.939 g/cm3and synthesized with a metallocene catalyst with 5 to 40 pts.wt. high-density polyethylene having a density of 0.950 to 0.965 g/cm3and 5 to 40 pts.wt. low-density polyethylene having a density of 0.925 to 0.930 g/cm3. The high-frequency coaxial cable 10 is produced by surrounding a conductor 11 with a foam insulation layer 12 made of a foam from the resin composition. COPYRIGHT: (C)2005,JPO&NCIPI
