RESIN COMPOSITION AND HIGH FREQUENCY COAXIAL CABLE

摘要

PROBLEM TO BE SOLVED: To provide a resin composition which can also be made into an isolated cell as a foaming insulator using high density polyethylene and has a low voltage standing-wave ratio (VSWR) which is an index for stability in the lengthwise direction of a cable and a low attenuation; and to provide a high frequency coaxial cable.SOLUTION: A foaming insulating layer is formed with the resin composition which includes a mixture of crosslinking-treated polyethylene and non-crosslinked polyethylene and has a density of 0.960 g/cmor more and a melting rupture tension of 20-100 mN.
