Hot isotactic pressed Boron Nitride (HIP BN) is a high purity, hot isostatic pressed Boron Nitride material. This advanced material has excellent thermal shock resistance and very low thermo-cycling behaviour combined with low thermal expansion.
HIP BN has a high chemical resistance to glass and molten metals and maintains its low frictional properties even at high temperatures.
HIP BN also has high dielectric strength and excellent electrical resistivity. It exhibits low thermal expansion and high thermal conductivity. In addition, it is easily machined.
