Abstract: Diecuts and methods for closing of holes in metal sheets or in plastics parts are disclosed. The diecuts have a carrier composed of an assembly that comprises a metallic first layer having a thickness of 10 to 40 μm, a second layer of a woven or laid glass fabric having a basis weight of 30 to 200 g/m2, an optional first adhesive third layer, an unexpanded expandable graphite fourth layer having a thickness of at least 0.2 to 3.0 mm, and a second adhesive fifth layer. The expandable graphite being present in the fourth layer to an extent of at least 80 wt % and fifth layer being formed by an adhesive having a basis weight of 300 to 1800 g/m2 and/or a thickness of 400 to 1800 μm.

Abstract: The present invention relates to a diecut especially for the permanent closing of holes especially in metal sheets or in plastics parts, having a carrier composed of an assembly, more particularly laminate in the specified layer sequence, of optionally at least one first layer, which is formed by a metallic layer having a thickness of 10 to 40 μm, optionally at least one second layer, which is formed by a woven glass fabric or laid glass fabric having a basis weight of 30 to 200 g/m2, optionally at least one third layer, which is formed by a first pressure-sensitive adhesive having a basis weight of 70 to 200 g/m2, at least one fourth layer, which is formed by a flame-retardant foam having a thickness of at least 0.5 to 2.5 mm, and at least one fifth layer, which is formed by a second, acrylate-based pressure-sensitive adhesive having a basis weight of 300 to 1800 g/m2, preferably 360 to 1500 g/m2 and/or a thickness of 400 to 1800 μm, preferably 800 to 1500 μm.
