| abstract |
The invention is directed to a sealing device comprising a polymeric carrier layer (2) having a first and a second major surface and a first functional layer (3) comprising 25 – 95 wt.-% of at least one polymer P1 and 5 – 75 wt.-% of at least one solid filler F, wherein the polymeric carrier layer (2) has a thickness of 10 – 450 µm µm and wherein the sealing device (1) has a mass per unit area of not more than 450 g/m2. The invention is also directed to a method for producing a sealing device and to use of a sealing device as a waterproofing membrane, vapor barrier, vapor retarder, gas barrier membrane, volatile organic compound (VOC) barrier membrane, or as a geomembrane. |
