Insulator Pyrolytic Boron Nitride PBN/PG Heaters Disc

The PBN/PG ceramic heater combines three layers of ultra-high purity ceramics, PBN-PG-PBN to produce an advanced micro-ceramic
heating element system. PBN as an insulating substrate and PG as the resistive element.Both our PBN heater (Pyrolytic Boron
Nitride) and PG heater (Pyrolytic Graphite) are manufactured by high temperature CVD. These high performance elements exhibit
outstanding thermal properties in a ceramic heater, including high thermal conductivity and anisotropy.

Mechanically durable and thermally shock resistant, PBN/PG heaters are unaffected by vibration under most conditions and can be tailored to thermal gradients for specific requirements. With an ultra-fast response and low thermal mass, PBN/PG heaters demonstrate a power output of 35 watts/cm 2 (225 watts/in 2 ) and higher.

Size customization, please let me know the use temperature, current and voltage.
