WELDING COMPONENT FOR FUEL ENCLOSING CONTAINER

摘要

PROBLEM TO BE SOLVED: To solve a problem that the fuel permeability resistance is not always sufficient in a conventional welding component for a fuel enclosing container. SOLUTION: A resin-made welding component B1 comprises an annular welding part 1 to be welded to a fuel enclosing container T and a tubular part 2 which is coaxially continuous to the welding part 1. The welding part 1 is formed of a material mainly consisting of maleic acid modified polyethylene resin, and the tubular part 2 is formed of a material mainly consisting of non-reinforced semi-aromatic polyamide resin having a glass transition point at≥80°C and having a melting point at≤320°C. Permeability resistance of the fuel and the welding strength of the fuel enclosed container can be compatibly achieved thereby. COPYRIGHT: (C)2005,JPO&NCIPI
