Momentive Performance Materials’ boron nitride (BN)
Powders of grades HCP,HCPH, HCPL, and AC6004 are generally single-crystal hexagonal platelets with very high purity. The mean particle sizes for these ultra-fine powders are in the range of 6 to 13 μm, and they are >99.9% -325 mesh.

Applications
These grades are used in a broad range of
demanding applications, including release
agents for high temperature metal and glass
processing and thermal management materials
for electronics. Additionally, these grades
are employed as additives in solid lubrication
applications, and as base materials for
hot-pressed solids and composites and
refractory coatings.Momentive Performance
Materials produces over 80 standard and
custom grades of BN powders to meet a
wide range of application requirements,
and has over40 years of expertise
