Abstract:
The present invention aims to provide a laminate in which a fluororesin layer and a fluororubber layer are firmly bonded even when the fluororesin layer contains a fluororesin having excellently low fuel permeability. The present invention relates to a laminate including a fluororubber layer (A) and a fluororesin layer (B) stacked on the fluororubber layer (A). The fluororubber layer (A) is a layer formed from a fluororubber composition. The fluororubber composition contains a fluororubber (a1) and a basic multifunctional compound having at least two nitrogen atoms in the molecule with a distance between the nitrogen atoms in the molecule of 5.70 Å or greater. The fluororubber (a1) has an absorption coefficient at 1720 cm−1, determined after being brought into contact with triethyl amine, of 0.35 or lower. The fluororesin layer (B) is formed from a fluororesin (b1) having a fuel permeability coefficient of 2.0 g·mm/m2/day or lower.
