Hexagonal Boron Nitride Powder SHOBN

SHOBN / UHP is white-colored, high-purity hexagonal boron nitride crystallized powder, which has the same type of layer structure as graphite and provides a very good lubrication/mold-release characteristic. While graphite is highly active, easily reacts with metals/oxides and has electrical conductivity, boron nitride has electrical insulation as well as chemical/thermal stability, and is stable up to approximately 3000°C in the inert atmosphere.

Characteristics

1. 1. High thermal stability
   Stable up to approximately 3000°C in the inert atmosphere.
2. 2. High corrosion resistance
   Stable against most organic solvents and corrosive chemicals, and unwettable by most molten metals and glasses.
3. 3. High electrical characteristics
   Has high electrical insulation and voltage resistance at high temperature and no changes in permittivity and dielectric loss up to high-frequency area.
4. 4. Lubricity and mold-release efficiency
   Friction coefficient does not change up to considerably high temperature in nitrogen atomosphere, which enables use up to approximately 950°C in the air.
5. 5. High thermal conductivity and high heat radiation
   High thermal conductivity and high heat radiation can be applied to various kind of heat radiators

Application

1. 1. Various resin and rubber additives
2. 2. Filler for insulation and high thermal conductivity
3. 3. Use for high temperature lubrication
