Boron nitride tube is mainly used as insulating sleeves. Boron Nitride (BN), Hexagonal boron nitride (H-BN), and hot-pressed boron nitride are good self-lubricate ceramics that will withstand heat and maintain their lubricating capability during a high vacuum environment. Hexagonal boron nitride (H-BN) behaves almost like graphite mechanically, but it offers better electric resistance. The Boron Nitride Tubes (BN Tubes) from Heeger Materials are made up of hot-pressed boron nitride blank.
Hot pressed at high temperature (1900℃).

Boron Nitride ceramic from Heeger Materials can endure heat within a high vacuum environment, plus it's chemically inert — excellent corrosion resistance and electric resistance. Therefore, Boron Nitride ceramic product is a perfect choice for a wide selection of industries, such as:
Boron Nitride (BN) Tubes are carefully packaged in cartons boxes with foam protection to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
