Packing

 

As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Disc is carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for BN products, vacuum packing is also engaged for some of the parts.
