A composition with better barrier properties against fuel vapors comprises a mixture of about 20 to 80% by weight of a first fluorointerpolymer with about 80 to 20% by weight of a second fluorointerpolymer. The first fluorointerpolymer comprises a copolymer, terpolymer or mixture thereof formed by the copolymerization of two or more monomers, chosen from the group consisting of hexafluoropropylene, vinylidene fluoride and tetrafluoroethylene. The second fluorointerpolymer comprises a copolymer, terpolymer or mixtures thereof formed by the copolymerization of two or more monomers, chosen from the group consisting of hexafluoropropylene, vinylidene fluoride and tetrafluoroethylene. The first fluinterinterpolymer has elastomeric characteristics and the second fluorointerpolymer has thermoplastic characteristics; and hose for fuel with better debarrera properties against fuel vapors, manufactured with the composition. |
