HeBoFill® 641

Boron Nitride Powder

HeBoFill® 641 is characterised by its high purity and the size of individual crystallites. As a result of its high crystallinity, this material offers excellent lubricity. In addition, the powder has a relatively small grain size distribution, whilst the specific surface area is relatively low die to the size of the crystallites. This ensures that, when used as a filler, the viscosity of the base materials remains relatively unaffected.
 
Typical applications for HeBoFill® 641
 
  • additive to improve the high temperature performance of oils and greases
  • filler to increase the thermal conductivity of polymers
  • filler for coatings due to the low wettability of the boron nitride
 
Advantages of HeBoFill® 641
 
  • electrically insulating
  • high thermal conductivity
  • high purity
  • large individual crystal sizes
  • low specific surface area
  • no abraded metal particles in the end-product
  • minimal tool wear in comparison to other fillers due to extremely low hardness
  • excellent release and lubricating effect, also at high temperatures due to high oxidation resistance
