Boron Nitride Powder: The Clean, High-Performance Solution for Industry
Boron nitride powder stands out for its remarkable thermal endurance, chemical resistance, and natural lubricating properties. With a graphite-like hexagonal structure, it excels where extreme heat and sensitivity collide—offering cleaner insulation, reliable mold release, and performance in semiconductor manufacturing. Unlike graphite, BN resists oxidation while electrically insulating, helping mitigate wear, reduce sticking, and manage heat—without risking contamination in demanding environments.
