<p>A multi-layer product comprises at least a first layer mainly made of a perfluorinated material and having a modified outer surface, and at least one covering layer mainly made of rubber and applied on the outer surface of the first layer without any adhesive being inserted between them. The outer surface of the first layer is modified in such a way that, compared with the unmodified perfluorinated material, it has a reduced quantity of fluorine F atoms, a distribution of hydrogen H atoms and/or nitrogen N atoms, and substantially the same quantity of oxygen O atoms. There is also a method for production of the multi-layer product.</p> |
