  • Hose for automotive fuel piping
    Patent number: 5588469
    Abstract: A hose for automotive fuel piping has an inner layer formed of a molding of a terpolymeric fluoro-resin prepared from tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride, so that it can be provided with suitable flexibility. Both the vulcanization composition of an epichlorohydrin rubber or NBR/PVC blend to be disposed outside the inner layer and the vulcanization composition of an NBR rubber or fluororubber to be disposed inside the inner layer contain 1,8-diazablcylco(5.4.0)undecene-7 salts and organophosphonium salts. A satisfactory bonding strength can be attained merely by the vulcanlzation bonding without any surface treatment such as corona discharge on the surface of the inner layer fluororesin.
