Boron Nitride Grades
NX1, NX5 & NX10

NX1

NX1 is an ultrafine BN crystal with a submicron mean particle size. NX1 is optimized to be easily dispersible and the particles remain in suspension over extended periods of time.

NX5

NX5 is made up of small agglomerates of ultrafine BN crystals. These agglomerates can enhance thermal conductivity of thin films.

NX10

NX10 is a medium sized agglomerate with improved flowability for incorporation into coatings or resins. NX10 agglomerates can be compounded into plastics to improve lubrication and reduce coefficient of friction.

Note: Images are results from test data, actual results may vary. Typical properties and test data are not to be used as or to develop product specifications.

Potential Applications

NX grades are excellent candidates to consider for use in a wide range of demanding applications, including:

  • Lubricants and release agents for high-temperature metal and glass
    processing
  • Refractory coatings
  • Base material for hot pressed solids and metal-matrix or ceramic-metal composites
  • Processing and final product enhancement of plastics, including nucleation of solid and foamed products
  • Lubricating and reinforcing additives for tribological enhancement of polymer composites
