| 发明名称 | Multilayered resin tube-shaped body | ||
| 摘要 | Provided is an economical multilayered resin tube-shaped body that can be safely used in a high-temperature environment such as an engine compartment. A multilayered resin tube-shaped body (1) having excellent heat resistance is obtained by fanning an outer layer (2) from a thermoplastic resin having a melting point of 190-300° C. and fonning an inner layer (3) from a thermoplastic resin having a melting point of 150-300° C. and low liquid or gas permeability. The thermoplastic resin that forms the outer layer (2) is preferably a resin having a hoop stress of 10 MPa or greater in a 120° C. atmosphere. Furthermore, the thermoplastic resin that forms the inner layer (3) is preferably a resin having a gasoline permeability of 1.0 g/m2·day or less. | ||
