PURPOSE: To provide a corrugated tube having excellent heat resistance and high flame retardancy. CONSTITUTION: A flame retardant corrugated tube consists of a composition. The composition contains a polyolefin, an antimony trioxide, a halogen flame retardant, for example, 1,2-bis(pentabromophenyl) ethane, and an inorganic filler having an average particle diameter of 0.1-20μm for example, a talc and a calcium carbonate. When the antimony trioxide is 3-15 pts.wt. based on 100 pts.wt. of the polyolefin and mixing quantities of the halogen flame retardant and the inorganic filler are respectively X pts.wt. and Y pts.wt, the composition satisfies the following expressions: 23<=X+√Y<=45 and 0.1<=Y<=60.0. |
