Momentive Performance Materials’ boron nitride (BN)
powder grades AC6028, AC6103, and AC6091 are large agglomerates of well-defined individual (~10 μm) crystals. These low-to-medium-density grades are processed to achieve tailored surface areas; they are pourable and exhibit good lubrication and thermal conductivity properties in finished products.

Applications
These grades are ideal for use in thermal spray applications as well as metal-matrix and ceramic composites for wear applications such as high-performance brake linings. They are also used in heating elements and adhesives, pastes, and potting compounds with increased thermal conductivity and high electrical resistivity.

Momentive Performance Materials produces over 75
standard and custom grades of BN powders to meet a wide range of application requirements, and has over 40 years of expertise in the synthesis and refinement of boron nitride powders.
