MULTILAYER TUBE FOR TRANSPORTING WATER OR GAS.

摘要

The invention concerns a multilayer tube comprising (from the inside to the outside of the tube): optionally a layer C₁ of a fluorinated polymer; a layer C₂ of a fluorinated polymer whereon is radiation grafted at least one unsaturated monomer, optionally mixed with a fluorinated polymer; optionally a layer C₃ of adhesive binding, said layer C₃ being directly bound to the layer C₂ containing the radiation grafted fluorinated polymer; a layer C₄ of a polyolefin optionally mixed with a functionalized polyolefin, directly bound to the optional layer C₃ or to the layer C₂; optionally a barrier layer C₅; optionally a polyolefin layer C₆.
