MULTILAYER TUBE FOR TRANSPORTING WATER OR GAS

摘要

The invention concerns a multilayer tube comprising (viewed form inside outwards of the tube): optionally a layer C₁ comprising at least one fluorinated polymer; a layer C₂ comprising at least one functionalized fluorinated polymer, optionally mixed with at least one fluorinated polymer; a barrier layer C₃ comprising a barrier polymer selected among EVOH or a mixture based on EVOH, PGA or PDMK; a layer C₄ of an adhering binder; a layer C₅ comprising at least one polyolefin, optionally mixed with at least one functionalized polyolefin; optionally a barrier layer C₆; optionally a layer C₇ comprising at least one polyolefin, optionally mixed with at least one functionalized polyolefin.
