Interface dressing

An interface dressing consisting of an elastomeric matrix, the elastomeric matrix being provided with a plurality of through-holes, each through-hole having a contour about a central axis,

• wherein at least one part of the plurality of through-holes is arranged so as to form at least one pattern wherein each through-hole is adjacent to at least one other through-hole, the adjacent through-holes having rectangular contours, images of which, when moved translationally in a plane perpendicular to the central axes in order to merge images of said central axes by means of said translational movement, do not become superimposed,
• wherein, in absence of external strain, the interface dressing has:
• a thickness of between 0.4 mm and 2 mm,
• a yarn width between two adjacent through-holes of between 0.3 mm and 4 mm,
• a grammage of between 200 g/m2 and 1200 g/m2,
• wherein, in absence of external strain, each through-hole has a length of between 2 mm and 4 mm and a width of between 1 mm and 2 mm,
• wherein lateral edges of the interface dressing remain straight under an applied tensile force test,
• wherein the applied tensile force test is conducted by means of a tensile testing machine on a sample of the interface dressing having a width of 10 cm and applying a tensile force in a direction of stretching parallel to a length of the sample at a speed of 100 mm/min with a distance between jaws of 5 cm up to an elongation of 70% of elongation at break, holding the sample at the elongation, and observing the lateral edges,
• wherein the elastomeric matrix consists of an elastomeric composition, the adjacent through-holes of the pattern being separated from one another by a yarn of elastomeric composition,
• wherein the elastomeric composition comprises a blend of two copolymers, and
• wherein the blend comprises at least one copolymer which has a viscosity of between 0.01 and 1 Pas measured in a solution at 5% mass/mass in toluene and at least one copolymer having a viscosity of between 0.01 and 0.5 Pas measured in a solution at 15% (mass/mass) in toluene.
