Abstract: front page image
(EN)A two-layer structured fuel hose having an inner layer of a fluororesin and an outer layer of a thermoplastic resin, characterized in that the fluororesin has a tensile strength at break greater than 21 Mpa, the inner layer has electrical conductivity and gas-barrier property, and the fluororesin is capable of undergoing melt adhesion with the thermoplastic resin. The hose preferably has a corrugated region at a midpoint thereof for improving bending property. The above hose exhibits excellent adhesiveness between the layers with no use of an adhesive agent and has anti-static property.
(FR)L'invention concerne un tuyau souple de carburant à deux couches: une couche interne de fluororésine et une couche externe de résine thermoplastique, sachant que la fluororésine a une résistance à la rupture supérieure à 21 Mpa, que la couche interne a des propriétés de conductivité électrique et de perméabilité aux gaz, et que la fluororésine est capable de subir une adhésion par fusion avec la résine thermoplastique. De préférence, le tuyau souple présente une zone ondulée en un point médian, pour améliorer le potentiel de courbure. Ce tuyau offre une excellente adhésion entre les couches, sans recours à un adhésif, et il est antistatique.
