Pyrolytic Boron Nitride

High-Performance, High-Temperature Ceramic Compound

PBN/PG "printed circuit" heaters utilize PBN as an insulating substrate and PG as the resistive element. In non-oxidizing environments, this combination of unique materials delivers performance advantages not available in conventional thermal systems.
