<p>PROBLEM TO BE SOLVED: To provide a laminate tube not only excellent in terms of thermal stability at the time of a molding work, low-temperature impact resistance, degraded fuel resistance, chemical liquid transmission prevention, and interlayer adhesiveness but also electroconductive.SOLUTION: The provided electroconductive laminate tube consists of at least three layers including: a layer consisting of an aliphatic polyamide; a layer consisting of a semi-aromatic polyamide having a specified structure consisting of diamine units including at least 80% of C9-13 aliphatic diamine units and dicarboxylic acid units including at least 80% of terephthalic acid units and/or naphthalenedicarboxylic acid units; and a layer consisting of an electroconductive semi-aromatic polyamide copolymer composition consisting of: a semi-aromatic polyamide copolymer having a specified structure; and an electroconductive filler.</p> |
