A radiation resistance halogen free resin composition, and the electric wire and cable using this
Document Type and Number:
Japanese Patent JP6152802
Kind Code:
B2
Abstract:
A radiation-resistant halogen-free resin composition comprising 3-10 parts by mass of an aromatic amine-based antioxidant, 5-20 parts by mass of an aromatic process oil, 10-30 parts by mass of a melamine cyanurate compound and 100-200 parts by mass of a metal hydrate per 100 parts by mass of a base polymer mainly comprising an ethylene polymer, wherein the ethylene polymer comprises at least one of an ethylene-propylene-diene copolymer, an ethylene-alpha-olefin copolymer and an ethylene-vinyl acetate copolymer, and wherein the ethylene polymer further comprises an ethylene polymer modified with a polar functional group. The polar functional group may comprise an epoxy, carboxyl or maleic anhydride group. Preferably the ethylene polymer modified with the polar functional group comprises ethylene-alpha-olefin copolymer. Also disclosed is an electric wire 10 and also a cable, both comprising covering material 2 comprising the radiation-resistant halogen-free resin composition.
