摘要:
There is provided a multilayer tube for transporting a fuel, a chemical liquid or a gas, which is based on a thermoplastic resin, in particular a polyamide resin, wherein its inner layer comprises an electroconductive thermoplastic resin in which a fine carbon fiber has been blended as an agent imparting an electroconductivity, and it excels in a molding processability, a fuel oil resistance and an antistatic property. This multilayer tube comprises at least two layers of (a) an outer layer comprising a thermoplastic resin, and (b) an inner layer comprising an electroconductive thermoplastic resin so that a surface resistivity is not more than 10 8 ©; the electroconductive thermoplastic resin comprising a fine carbon fiber, wherein a graphite-net plane consisting solely of carbon atoms forms a temple-bell-shaped structural unit comprising closed head-top part and body-part with open lower-end, 2 to 30 of the temple-bell-shaped structural units are stacked sharing a common central axis to form an aggregate, and the aggregates are connected in head-to-tail style with a distance to form the fiber.
