PROBLEM TO BE SOLVED: To provide a fire-retardant composition excellent in heat resistance, fire retardancy and thermal deformability.SOLUTION: A silane crosslinking fire-retardant composition is formed by mixing 20-50 pts.mass of a bromine-based flame retardant, 1-40 pts.mass of antimony trioxide, 1-15 pts.mass of a benzimidazole-based compound, 1-15 pts.mass of zinc oxide, and 0.005-0.3 pts.mass of a silane crosslinking catalyst, based on 100 pts.mass of a resin component. The resin composition contains 5-40 mass% of one or more polypropylene-containing resins selected from a group consisting of 40-80 mass% of a silane modified ethylene-based copolymer resin, a polypropylene-based resin and a polypropylene-based thermoplastic elastomer, with the balance including a polyethylene-based resin. |
