Boron Nitride Powders - Momentive Usa Application: Industrial

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 13m, and they are >99.9% -325 mesh.
HCP
Grade HCP is Momentives basic high-purity grade and is flexible enough to fulfill a wide range of advanced material applications. Its mean particle size is 7-10 A A m.
HCPH
HCPH is processed to consist of a more agglomerated structure than HCP, and therefore a higher specific surface area. This makes it ideal for creating good particle-to- particle contact in a matrix.
HCPL
HCPL is refined to achieve a lower surface area than HCP, making it more lubricious and stable at even higher temperatures. It also exhibits improved blending in many formulations.
AC6004
AC6004 has the lowest coefficient of friction of any Momentive boron nitride powder, making it an outstanding lubricant. It possesses a slightly larger particle size (12- 13 A A m), a lower surface area, and a tighter particle size distribution than HCP.
