Pyrolytic Boron Nitride (PBN) is usually used as a coating material to protect the graphite in high temperature, high vacuum, and high purity environments. PBN coating can avoid the graphite heating unit to volatilize at high temperatures. Heeger Materials supplies pyrolytic boron nitride(PBN) coating with high quality and at a competitive price.  

Pyrolytic Boron Nitride (PBN) Coating Product Feature:

• High insulative.
• Low outgassing in high temperatures.
• The coating can be combined with the substrate tightly, not easy to peel off.
• High resistance to chemical corrosion in high temperatures.
• High density and effectively prevent volatilization of the substrate.
