ArChine Powder BN
Product Description
ArChine Powder BN is a kind of hexagonal boron nitride powder with specific properties, 98% through 325 mesh grid, and can meet a wide range of advanced material applications.
Applications
ArChine Powder BN has a very broad scope of use, including as release agents in high-temperature processing of metal and glass, refractory materials and heat treatment materials (adhesives, gap and bottom fillers, sealants, silicone polymers and silicone pads, etc.) and heat transfer materials in electronic industries. In addition, these products have been used as solid lubricant additives, hot pressed solids, metal templates, metal-ceramic composites and base materials of refractory coatings.
