      Grade HN

      Formula: BN, CAS No.: 10043-11-5, smooth soft powder in white color. Its microstructure is single platelet with hexagonal crystal system. It provides perfect electric insulation, thermal conductivity, lubricity as well as chemical resistance. It is chemical inert material; almost stable to all the organic solvent, melting metal and corrosive chemicals.

      Applications
       
        ★ As filler in thermal conductivity products
        ★ As raw material for BN coating in plasma spray
        ★ As principal raw material in BN coating
        ★ As principal raw material at high temperature insulation composite
        ★ As release agent in optical glass production process
        ★ As additive in premium lubricant oil
        ★ As raw material in hot pressed BN products
       
      Characteristics
       
      Grade HN is produced up to 1800°C. It has single platelet microstructure and high crystallinity. Those platelets have an average size of app. 9µm and a high aspect ratio. The product is matching the quality of competitive materials manufactured in other parts of the world and can be used as a 1:1 replacement in a lot of established applications. Furthermore, Grade HN has uniform particle size and the particle size is similar to PTFE. Hence it is the perfect additive to be used in high voltage switch nozzle process. Due to its high thermal conductivity, it is a very good fit for thermal conductivity polymer and rubber application. Also very good for high-end BN hot pressed parts with lower oxygen content which is usually less than 0.5%.
