Abstract (en)
[origin: WO2019149900A1] The invention relates to a composition for producing a hearing device component (5, 13), comprising 60 % by volume to 95 % by volume of at least one thermoplastic plastic material selected from a group consisting of liquid-crystalline polymers (LCP), polyesters (PE), polyamides (PA) and polyphthalamides (PPA), and comprising 5 % by volume to 40 % by volume of at least one filling material selected from a group consisting of barium titanate, carbon nanotubes, barium strontium titanate (BaxSr1-xTiO3), titanium dioxide, lead zirconate titanate (PZT) and lead magnesium niobate titanate (PMNT), wherein the composition has a loss factor tan δ below 0.01 and a relative permittivity εr above 5, in particular in a range between 5 and 10, in a frequency range between 2.0 GHz and 3.0 GHz, in particular in a frequency range between 2.4 GHz and 2.5 GHz. The invention further relates to a hearing device component (5, 13) comprising a correspondingly assembled base body (1, 15).
