Product Overview: PBN insulation rings/sheets are widely used as insulating components in high vacuum and high-temperature environments due to their excellent high-temperature electrical insulation properties and ultra-high purity.

Product Overview: Conventional insulating materials typically have drawbacks such as poor high-temperature resistance, low purity, gas release at high temperatures, poor toughness, loss of insulation properties at high temperatures, and susceptibility to corrosion. PBN (Pyrolytic Boron Nitride) insulating boards address these issues effectively.
