Boron Nitride Powder – BN1205 (30 um)
Boron Nitride (BN) powder is inert, white material having a hexagonal, plate-like crystal structure resembling that of graphite. It offers the unique combination of high thermal conductivity and dielectric strength in one material. Today's smaller, hotter, and faster electronic assemblies require greater heat dissipation than ever before. Polymers filled with BN powders solve these problems in a wide variety of applications.
| Boron Nitride (BN) Powders | BN1203 (2 um) | BN1204 (0.5 um) | BN1205 (30 um) | | Surface Area (m2/gram) | 15 | 20 | 1 | | Tapped Density (g/cc) | 0.2 | 0.3 | 0.6 | | Mean Particle Size, D50 (diameter, um) | 2 | <1 | 30 |
Boron Nitride is unmatched when it comes to high thermal conductivity, low dielectric loss, and low thermal expansion. In fact, it has the highest thermal conductivity of any commercial electrical insulator in polymer systems.
Features and Benefits
Boron Nitride powders offers following properties:
· Low dielectric
· High thermal conductivity (125 to 300 W/mk)
· Stable (non-oxidizing)
· Non-abrading
· Lubricious
· Non-toxic
· Temperature resistant
Thermal Conductivity
Boron Nitride has the highest thermal conductivity of any commercial non-electrical insulator in polymer systems. Boron Nitride is unmatched when it comes to high thermal conductivity, low dielectric loss and low thermal expansion.
Thermal Conductivity of BN single crystal > 300 W/mK
