Application H-BN-A, B, C: It is a medium crystal. Because the particles are spherical, they are particularly suitable as a release agent for casting,casting and injection molding, and composite ceramics. They are also easy to hot press.H-BN-D: Due to its similar particle size to PTFE and uniform particle size, it is especially suitable for high-pressure switch nozzles; itis also suitable for heat-conductive plastics or heat-conductive rubber; and because of its low oxygen content (generally less than 0.5%) It is also especially suitable as a special ceramic raw material.H-BN-E: High crystallinity of hexagonal boron nitride has better performance than ordinary products. Can be used in a variety of high-end areas, including cosmetics and thermal materials.H-BN-F:Often used as an additive in the high-end electronics industry. Currently, other application areas of this product are beingdeveloped. Packing & Delivery Packing: Aluminum foil bag lined with plastic bag, net weight 1kg per bag.
Storage: Stored in a cool and ventilated place. Keep sealed. The shelf life is 12 months after manufactured date. It is still
available if the retest results of the properties are qualified after expired date.
Transportation: We have 10 years experiences of oversea transportation of chemicals and customs clearance, you will receive the goods as fast as possible. Company Profile Contact us
