Features
Boron nitride powders for thermal management applications are inert, white ceramic materials with a platy, hexagonal crystal structure with the following advantages:
- High thermal conductivity for efficient heat dissipation
- Low density and light weight for high filling properties
- Low dielectric constant for high performance of electronic devices
Powders are available in platelets and agglomerated form with a range of density and porosity options. Agglomerates provide more efficient particle packing due to granular morphology. Platelets with platy lamellar structure promote an efficient heat spreading in polymer materials.
