FLAME-RETARDANT RESIN COMPOSITION, AND INSULATING WIRE, METAL CABLE, OPTICAL FIBER CABLE AND MOLDED ARTICLE USING THE SAME

摘要

A flame-retardant resin composition may include a base resin composed of polyethylene and an acid-modified polyolefin, a silicone compound, a fatty acid-containing compound, and a hindered amine-based compound that includes a hindered amine structure. The polyethylene may include a high-density polyethylene, a medium-density polyethylene and a low-density polyethylene, where the high-density polyethylene has a density of 945 kg/m³ or more, the medium-density polyethylene has a density of 914 kg/m³ or more and less than 945 kg/m³, and the low-density polyethylene has a density of 864 kg/m³ or more and less than 914 kg/m³. The base resin may contain the high-density polyethylene in an amount of 40 mass % or more and 60 mass % or less, the medium-density polyethylene in an amount of 1 mass % or more and 35 mass % or less, and the low-density polyethylene in an amount of 10 mass % or more and 30 mass % or less.
