HR-F Spherical Aluminum Nitride Powder for Thermal Interface Material
Product Description
HR-F series spherical aluminum nitride filler is a product obtained through special sphere formation, nitriding purification, classification and other processes. The resulting aluminum nitride has a high spheroidization rate, small specific surface area, narrow particle size distribution and high purity. This product is widely used as a thermal interface material due to its high thermal conductivity, good fluidity and other characteristics.
Feature
High thermal conductivity
● Low specific surface area
● Good fluidity, high filling rate
● The particle size is uniform ,and the distribution is very narrow, conducive to achieve a stable match with other fillers in the application
