ABSTRACT:
A laminated product, in particular a fuel hose, comprises a fluororesin layer and, superimposed on the fluororesin layer, a layer of cured rubber obtained or obtainable by curing a rubber composition comprising a blend of 60 to 95 wt % highly-saturated nitrile copolymer rubber with 40 to 5 wt % epihalohydrin rubber. The rubber blend layer can be made to adhere well to the fluororesin layer by curing it in situ. The nitrile rubber component confers heat resistance on the rubber layer while adhesion is maintained.
