Provided are formed bodies comprising hexagonal boron nitride wherein the formed body has a Brinell hardness of at least 2 HBW 2,5/2, and wherein the formed body is obtainable by a process at temperatures of at most 100&#xb0; C., and wherein the Brinell hardness is measured according to DIN EN ISO 6506-1 (2013). Further provided are processes for making said formed body.

Formed hexagonal boron nitride body, hexagonal boron nitride granulates for making the same, and process for producing the same

The invention relates to a method for producing a component part having a wall thickness of at most 3 mm on at least one part of the component part, comprising the method step of injection molding by means of an injection mold in an injection molding machine using a polymer/boron nitride compound, wherein the polymer/boron nitride compound comprises a thermoplastically processable polymer material and a heat-conducting filler, wherein the filler comprises platelet-shaped hexagonal boron nitride particles and wherein the injection rate during injection-molding is at most 200 mm/s. The invention further relates to a component part produced using such a method and a polymer/boron nitride compound for producing such a component part. The invention further relates to the use of such a component part for heat dissipation of component parts and assemblies to be cooled.
