What is Hexagonal Boron Nitride Powder?
This product has structure and properties similar to graphite. Hexagonal boron nitride powder is one of the most popular dry lubricants available today, due mostly to its lubricant properties and its inertness to molten metals and salts. It is therefore often used as a mold release agent. HBN (White Graphite) also has high thermal conductivity. This means it will act as a heat sink, helping to keep parts cooler. It will also improve the strength and hold ability of powder composites, and has high load bearing properties. We generally sell Hexagonal Boron Nitride as a dry powder, but upon request, we can provide it as either a thick paint or thin paste (sprayable), convenient for use with tooling and stamping machined parts. Sizing Nomenclature: A -5 (Negative Five) micron material will have the majority of its particles smaller than 5 micron, generally having a D50 of 2-3 micron. Think of D50 as an average, although technically, the D50 is considered to be the average particle diameter
