<p>Technical adhesive tape comprises a band shaped carrier made of plastic, and a pressure sensitive adhesive coating made of an adhesive, applied at least on one side of carrier with a surface weight of at least 100 g/m 2>. The carrier comprises a molded polyolefin film and is elastically and plastically stretchable such that a differential value between the total elongation under load and permanent elongation after the subsequent discharge is 15-50%. The total elongation of sample strips of at least 25 mm width and 250 mm length, is determined during the measurements of the differential value.

The carrier comprises a molded polyolefin film and is elastically and plastically stretchable such that a differential value between the total elongation under load and permanent elongation after the subsequent discharge is 15-50%. The total elongation of sample strips of at least 25 mm width and 250 mm length, removed longitudinally to the production direction of the film, is determined during the measurements of the differential value according to DIN 53360, under a static load of 1 kg applied for 30 minutes. The permanent elongation is determined 30 minutes after the discharge of the sample strips.</p> |
