Abstract
A flame-retardant composition that is more excellent in heat resistance than a conventional flame-retardant composition. The flame-retardant composition contains silane-crosslinked polyolefin, polyolefin, a metallic hydrate, a phenolic antioxidant, a sulfurous antioxidant, a metallic oxide, and a copper inhibitor. The sulfurous antioxidant is preferably a benzimidazole compound, and the metallic oxide is preferably a zinc oxide. The silane-crosslinked polyolefin is preferably polyethylene having a density of 0.880 to 0.910 g/cm3 that is silane-crosslinked. The polyolefin is preferably polyethylene having a density of 0.880 to 0.910 g/cm3, or an olefin elastomer having a melting point of 140° C. or more.
