PURPOSE:To provide a fluorine-containing elastic-material coated electric wire of which a coating material is improved and which is therefore subjected to no foaming or no production of any grain when extrusion-worked, thus exhibiting a good surface appearance and a superior toughness. CONSTITUTION:A coating layer is formed by a composition wherein 5 to 100 weight part of ethylene-vinylacetate based copolymer, etc., and 0.5 weight part or more of crosslinking agent are added to 100 weight part of a mixture of a graft polymer, prepared by grafting a tetrafluoroethylene-propylene based copolymer, and polyvinylidene fluoride in the weight ratio of 90/10 to 10/90. Radiation rays are irradiated onto this coating layer. The above-identified electric wire which is subjected to no foaming in being machined and is superior in toughness is obtained. Use of this electric wire provides an advantage that the operating efficiency and economy are enhanced. |
