The present invention relates to a hose comprising: a thermoplastic fluorpolymer barrier layer; and a rubber layer adjacent to the barrier layer, the rubber layer comprising 100 parts by weight of an elastomer comprising FKM fluorelastomer; from about 1 to about 15 parts by weight, per 100 parts by weight of magnesium oxide, calcium hydroxide, lithium, dibasic lead phosphite, calcium oxide, and zinc oxide; from about 1 to about 6 parts by weight, per parts by weight of elastomer, of at least about 10 parts by weight, per 100 parts by weight of elastomer, of at least one of a tricalcium aluminate hydrotalcite or hexahydrate; where the weight ratio of the at least one acid acceptor to the at least one hydrotalcite ranges from about 1 to about 5. |
