Hose construction containing fluoroplastic terpolymers

摘要

The present invention relates to a hose construction containing a fluoroplastic barrier. The hose comprises (1) an inner core comprising (a) acrylonitrile-butadiene rubber and (b) from 0.05 to 25 phr of unsubstituted or substituted phenol salts of 1,8-diazabicyclo-Ä5,4,0Üundecene-7; (2) a barrier layer comprised of a terpolymer derived from tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride, wherein said barrier layer is directly adhered to said inner core; and (3) an elastomeric cover.
