Hexagonal Boron Nitride Powder (HBN)

Hexagonal Boron Nitride powder has a structure and properties similar to graphite. It has become one of the most popular dry lubricants due to its lubricating properties and inertness to molten metals and salts. It is used in many different applications, especially as a mold release agent. Hexagonal Structure Boron Nitride improves the strength and holdability of the present powder composites.
