Multi-layer tube (layers described from inside to outside of the tube) comprises: optionally a fluorinated polymer layer (I); a layer (II) comprising fluorinated functionalized polymer by e.g. carboxylic acid; optionally a layer (III) attached to (II) comprising a functionalized polyolefin, which is optionally mixed with polyolefin; a polyolefin layer (IV) attached to layer (III) or (II); a barrier layer; and optionally a polyolefin layer. Multi-layer tube (layers described from inside to outside of the tube) comprises: optionally a fluorinated polymer layer (I); a layer (II) comprising fluorinated functionalized polymer by carboxylic acid or its salt, ester or anhydride, carbonate, epoxy, silyl, alkoxysilane, amide carboxylic acid, hydroxy or isocyanate functional group or a fluorinated elastomer polymer having a tensile strength of 50-1000 MPa, 200-600 MPa from ISO R 527 standard at 23[deg]C; optionally a layer (III) attached to (II) comprising a functionalized polyolefin, which is mixed optionally with polyolefin; a polyolefin layer (IV) attached to layer (III) or (II); a barrier layer; and optionally a polyolefin layer. |
