high-power LED heat dissipation AlN

Xiamen Juci Technology Co., Ltd. presents its 150μm high-purity aluminum nitride (AlN) filler powder, a functional ceramic filler designed for high-performance thermally conductive composite materials. With key advantages including ultra-fine particle size (150 microns), high purity (≥99%), and low oxygen content, this product significantly enhances the thermal conductivity of polymer, metal, or ceramic matrix composites. It is widely used in electronic packaging, thermal interface materials (TIMs), high-power LED heat dissipation, and more. Key Features: 1、Exceptional Thermal Conductivity AlN boasts a theoretical thermal conductivity of 170-200 W/(m·K), over five times higher than conventional alumina fillers, dramatically improving the overall thermal efficiency of composite materials. 2、Precise Particle Size Distribution D50: 150μm, uniform particle size, smooth surface, and excellent dispersibility ensure efficient thermal conductive network formation in the matrix. 3、High Purity & Low Oxygen Content Purity ≥99%, oxygen content ≤1%, minimizing impurities' impact on dielectric properties and thermal conductivity, making it ideal for high-frequency electronic devices. 4、Superior Electrical Insulation Volume resistivity >10¹⁴ Ω·cm, low dielectric constant (~8.8), suitable for high-insulation-demanding electronic packaging. 5、Strong Chemical Stability High-temperature resistance (stable in air up to 1400°C), corrosion resistance, and excellent compatibility with epoxy resins, silicone gels, and other matrix materials.
