Abstract

The invention relates to a molding compound, comprising the following components: a) 60 to 96% by weight polyaryletherketone, b) 2 to 25% by weight hexagonal bornite, and c) 2 to 25% by weight talcum, wherein the sum of the parts by weight of components a), b), and c) is 100. Said compounds can be used to produce a film having a thickness of 5 to 1200 μm, which is suitable for producing dimensionally stable circuit boards.
