By nature, plastics do not have any significant thermal conductivity, although their use is increasing massively, particularly in the electronics sector. To solve this problem, we offer our HeBoFill® boron nitride powders. They are ideally suited as fillers to significantly increase the thermal conductivity of plastics while fully retaining their excellent electrical insulating properties. A major advantage for production: due to the low hardness of boron nitride, there is no tool wear during incorporation into the plastic and therefore no disruptive metal abrasion.
