Adhesive tape made of silicone intended for medical applications

An adhesive tape (1) for medical applications, comprising:

• a nonwoven sheet material (12) having an internal face (12a) and an external face (12b), the nonwoven sheet material comprising an internal layer (13a) that carries the internal face (12a) and an external layer (13b) that carries the external face (12b), the external layer (13b) having a density greater than a density of the internal layer (13a),
• the internal face carrying a barrier membrane (14) which adheres to the sheet material, the barrier membrane comprising a crosslinked silicone polymer, the barrier membrane carrying an atraumatic and biocompatible silicone adhesive gel layer (16),
• the external face (12b) carrying a nonstick and waterproof polymer layer (18) comprising a fluorosilicone or fluorocarbon polymer;
• wherein the sheet material (12) is composed of a mixture of fibers and having a low resistance to tearing and easily tearable by hand, wherein the sheet material includes a mixture of short cellulose fibers and of medium length polyethylene terephthalate (PET) fibers bonded to one another by calendering under hot pressure and/or by a chemical bonding agent, wherein the sheet material includes a ratio of 10 to 40% of PET for 90 to 60% of cellulose, wherein the sheet material has a weight of 30 to 70 g/m2 and a thickness of 0.10 to 0.30 mm, wherein the cellulose fibers have a length of the order of 1 mm to 20 mm, and the PET fibers exhibit cylindrical fiber structures with a linear density of between 0.1 dtex and 5 dtex, and with a length of the order of 2 mm to 20 mm;
• and
• wherein the sheet material (12) includes a profusion of small folds (15) in a transverse direction, thereby providing a low elongation stress in the longitudinal direction.
