ABSTRACT:
A pressurized fluid conduit includes a mono-layer of a semi-crystalline thermoplastic material that has a hardness of between 50 and 65 Shore D and a modulus at 150° C. of at least 60 MPa. The semi-crystalline thermoplastic material may be used for making a mono-layered pressurized fluid conduit via an extrusion molding process, such as an extrusion blow-molding process.
