| 摘要 |
A method for forming a laminated product is disclosed, comprising slot die extruding a laminant layer (6) of a slot die extrudable cross-linkable polymer resin on to a first web of a first flexible material (8) . Preferably the method involves extruding between the first web of the first flexible material (8) and a second web of a second flexible material (7) . The first flexible material (8) is preferably aluminium foil. The polymer resin preferably comprises an organosilane grafted polymer resin, most preferably of polyethylene. Also disclosed is a laminated product obtainable by the method. The products of the invention find use in facings for insulation boards and exhibit improved properties, especially improved water resistant properties. |
