Boron Nitride Rods, Plates And Discs - Momentive Usa

We are Making, Exporting and Supplying Boron Nitride Rods, Plates and Discs - Momentive USA in Ludhiana, Punjab, India. Hot-pressed BN is compacted at temperatures up to 2000E C and pressures up to 2000 psi to form a dense, strong engineering material that is easily machined. It is available in standard and custom shapes and has several unique properties which make it valuable in a wide range of challenging industrial applications.

Four Material Grades
Grades HBC and HBT are our highest purity hot-pressed boron nitrides. They are diffusion bonded and feature a low dielectric constant, minimal moisture pick-up and low loss tangent making them ideal for electronic applications.

Grade HBT, although lower in strength and density than HBC, is available at lower cost and shorter lead times.

Grade HBN uses small amounts of boric oxide as a binder; it is used in applications where hydration and thermal shock are not a concern.

Grade HBR uses calcium borate as a strengthening binder and is moisture insensitive.

For applications demanding even higher strength and durability, Momentive offers grade BIN77 composite material; see publication 81520 for more details.
