High thermal conductivity × electrical insulation × low Dk/Df. Surface-modified products with low viscosity and high dispersion, suitable for CCL and TIM.
Hexagonal boron nitride (h-BN) is a filler manufactured by Tanyun in China, known for its excellent thermal conductivity, insulation properties, cost, and supply stability. In addition to standard products, we also offer high-dispersion products through surface modification and small particle size products in the development stage. Please feel free to contact us when you need assistance. 【Features】 ■ High in-plane thermal conductivity (up to 400 W/m·K) and electrical insulation (10^14 Ω·cm) derived from its hexagonal crystal structure ■ Usable in air up to 900°C and in inert atmospheres up to 2800°C ■ In addition to standard h-BN (D50 1–30 μm range), modified h-BN with enhanced resin affinity achieves low viscosity, high dispersion, and no sedimentation (up to 45 days) ■ Particle size grades (D50 1–4 μm) are also under development, suitable for thin film coatings and precision filling ■ Can be supplied at a lower cost and in stable large quantities compared to domestic products ■ High compatibility, low viscosity, high moisture and heat resistance, and low Dk, Df make it suitable for high-performance CCL *For more details, please download the PDF (English version) or feel free to contact us.
