摘要: Thermal conductive bobbin, for a magnetic power unit, made of an injectable and polymerizable thermoplastic composition having a plastic polymer in an amount of between 5% and 15% by weight with respect to the total weight of the composition, an aluminium nanoparticles dispersion in mineral oil in an amount of between 25% and 55% by weight with respect to the total weight of the composition, silicon carbide microparticles between 20% and 45% by weight with respect to the total weight of the composition; and additives up to 10% by weight with respect to the total weight of the composition, and wherein the thermal conductive bobbin has a dielectric rigidity higher than 5 kV/mm.
