BN5000 is a highly versatile hexagonal boron nitride (hBN) grade enhanced with a calcium borate binder, which significantly reduces its susceptibility to moisture absorption. This unique composition makes BN5000 an excellent choice for high-temperature applications that require low thermal expansion and exceptional thermal shock resistance.
