Hose construction containing fluoroplastic terpolymers

摘要

The present invention relates to a hose construction containing a fluoroplastic barrier and a hydrogenated acrylonitrile-butadiene rubber layer. The hose comprises (1) a rubber layer comprising (a) hydrogenated acrylonitrile-butadiene rubber; (b) from 2 to 15 phr of an organophosphonium salt; (c) from 5 to 30 phr of trioctyl trimellitate; and (d) from 5 to 30 phr of a dialkyl diether glutarate; (2) a barrier layer comprised of a terpolymer derived from tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride, wherein the barrier layer is directly adhered to the rubber layer.
