The invention relates to a die-cut part, in particular for permanently closing a hole, in particular in a metal sheet or in a plastic component, comprising a carrier consisting of the following components, more particularly a laminate according to a specified layer sequence: optionally at least one first layer, which is formed from a metallic layer having a thickness of 10-40 [mu] m, and optionally at least one second layer, which is formed from a metal layer having a thickness of 10-40 [mu] m; at least one second layer formed from a woven or laid glass fabric having a basis weight of 30-200 g/m2; optionally at least one third layer formed from a first pressure sensitive adhesive having a basis weight of 70-200 g/m2; at least one fourth layer formed from unexpanded, expandable graphite having a thickness of at least 0.2-3.0 mm, preferably 0.5-1.0 mm, the expandable graphite being present in the layer to an extent of at least 80% by weight; and at least one fifth layer formed from 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 [mu] m, preferably 800 to 1500 [mu] m.

    本发明涉及特别地用于永久地封闭孔的模切件,特别地在金属板中或在塑料部件中的孔,该模切件具有由如下的组件、更特别地按照指定的层序列的层压体组成的载体:任选地至少一个第一层,其由具有10‑40μm的厚度的金属性层形成;至少一个第二层,其由具有30‑200g/m2的基重的织造玻璃织物或铺设玻璃织物形成;任选地至少一个第三层,其由具有70‑200g/m2的基重的第一压敏胶粘剂形成;至少一个第四层,其由具有至少0.2‑3.0mm、优选地0.5‑1.0mm的厚度的未膨胀的可膨胀石墨形成,可膨胀石墨在至少80重量%的程度上存在于该层中;和至少一个第五层,其由具有300‑1800g/m2、优选地360‑1500g/m2的基重和/或400‑1800μm、优选地800‑1500μm的厚度的基于丙烯酸酯的第二压敏胶粘剂形成。
