Import Boron Nitride(Bn) — Buy in Bulk from Supplier in China

Shanghai Spark Advanced Material Co., Ltd produces Boron Nitride (BN) granules with purity exceeding 99.9 %. The granules are manufactured from high‑grade BN powder and are available in several particle‑size grades. Their chemical inertness and thermal stability make them suitable for demanding heat‑management applications. The product’s bulk form allows easy integration into molding, extrusion and coating processes.

Typical particle sizes range from 5 µm to 20 µm, providing a balance between flowability and surface area. The granules exhibit a thermal conductivity of about 30 W·m‑¹·K‑¹, a value common for high‑performance ceramic fillers. Standard bulk density is roughly 1.8 g cm‑³, matching the handling specifications of most industrial silos. Packaging is generally supplied in 1‑ton bulk bags, a format that aligns with standard bulk material logistics.

Primary customers are electronics manufacturers, aerospace component producers and metallurgical firms. Shanghai Spark can ship under FOB or CIF terms, with payment accepted via L/C or T/T. Prospective buyers should verify the exact particle‑size distribution and any required certifications with the supplier.

Shanghai Spark Advanced Material Co., Ltd is based in the Chanba Ecological Zone, Weiyang District, Xi’an, Shaanxi Province, 710038, China. The supplier carries a harbor trust tier and is listed as an imported‑tier source; its response rate is recorded as 0 % with no average response time, indicating that communication speed should be confirmed directly with the company. The profile highlights the company’s focus on advanced material products, including boron nitride derivatives for industrial use.

The company’s listing mentions that the BN granules are manufactured in‑house and that ISO and SGS certifications are generally available, but it does not provide specific details on production capacity, minimum order quantities, or lead‑time estimates. Importers should therefore request formal certification copies, batch test reports and any additional technical data required for compliance before proceeding with a purchase.
