<p>The present invention relates to a hose (20, 30) comprising: a thermoplastic fluoropolymer barrier layer (3, 12); and a rubber layer (1, 10, 14) adjacent to the barrier layer (3,12), the rubber layer (1, 10, 14) comprising 100 parts by weight of an elastomer comprising FKM fluoroelastomer; from 1 to 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 1 to 6 parts by weight, per 100 parts by weight of elastomer, of at least one diamine curative; and from 1 to 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 1 to 5. <IMAGE></p> |
