PROBLEM TO BE SOLVED: To provide a conduit tube having a high flame resistance and good slidability for facilitating pulling in an electric wire in which an incineration disposal can be made without a harmful gas while being burnt. SOLUTION: The conduit tube is manufactured by using a resin composition with 5 to 50 pts.wt. of an ethylenic copolymer having a polar group, 10 to 50 pt.wt. of metallic hydrate, 3 to 10 pts.wt. of phosphoric fire retardant, and 3 to 10 pts.wt. of lubricant blended for 100 pts.wt. of polyolefinic resin with a Shore D hardness of 60 or more and by using an extrusion molding process. |
