The present invention relates to a hose comprising: a thermoplastic
fluoropolymer barrier layer; and a rubber layer adjacent to the barrier
layer, the rubber layer comprising 100 parts by weight of an elastomer
comprising FKM fluoroelastomer; from about 1 to about 15 parts by weight,
per 100 parts by weight of elastomer, of at least one acid acceptor
selected from the group consisting of magnesium oxide, calcium hydroxide,
litharge, dibasic lead phosphite, calcium oxide, and zinc oxide; from
about 1 to about 6 parts by weight, per 100 parts by weight of elastomer,
of at least one diamine curative; and from about 1 to about 10 parts by
weight, per 100 parts by weight of elastomer, of at least one of a
hydrotalcite or tricalcium aluminate hexahydrate; wherein the weight
ratio of the at least one acid acceptor to the at least one hydrotalcite
ranges from about 1 to about 5.
