A flame-retardant resin composition for insulated wires, shielded wires and insulating tubes which are used in the field requiring high-frequency current transmission, for example, in the field of high-density wiring of internal circuits in electronic appliances. The composition comprises (a) a thermoplastic polyolefinic resin having a density of smaller than 0.89 g/cm3, which is prepared by copolymerizing ethylene and a non-polar alpha-olefin in the presence of a single-site metallocene catalyst, (b) a halogen-containing flame retardant, and (c) zinc oxide. After crosslinking, the composition is used in forming an insulating coating for insulated wires and shielded wires, and in forming insulating tubes. |
