Multi-layer tube, useful to transport (hot) water, chemicals and gas, comprises optionally fluorinated polymer layers, adhesive layer, polyolefin layer, barrier layer and polyolefin layer

摘要

Multi-layer tube (from the inside to the outside of the tube) comprises: optionally a fluorinated polymer layer (I); a fluorinated polymer layer (II), where at least one of the monomer is grafted on it by the radiation and optionally mixed with a fluorinated polymer; optionally a adhesive layer, where the layer is directly bound to the layer (II); a polyolefin layer (IV) is optionally mixed with a functionalized polyolefin, which is directly bound to the optional layer (III) or with the (II) layer; optionally a barrier layer; and optionally a layer comprising polyolefin.
