HCP Grade

榴莲视频下载污黄 produces over 70 standard and custom grades of BN powders to meet a wide range of application requirements, and has over 50 years of expertise in the synthesis and refinement of boron nitride powders.

榴莲视频下载污黄’ boron nitride (BN) powders of grades HCPL 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.?

Boron Nitride Powder Grades HCP

Grade HCP is Momentive’s basic high purity grade and is flexible enough to fulfill a wide range of advanced material applications. Its mean particle size is 7-10 μm.
