Our sintered spherical aluminum nitride powder makes it is easy to achieve 10 W/m-K (or higher) thermal conductivity in fillers.
RW Series aluminum nitride powders have high purity spherical shaped particles designed for excellent flowability and loading. Larger mean particle size, spherical shaped particles and a sharp particle size distribution (PSD) allows for an improved filling rate and the ability to reach new heights of thermal conductivity in fillers.
RW Series aluminum nitride powders have been specially treated for advanced water resistance. These surface treated AlN powders have the most effective anti-hydrolysis capability in the world as they can withstand an 85°C/85%RH (environment test) in water for more than 500 hours.
Key applications
RW Series can be used in a variety of silicone-polymers and epoxy-resins in order to develop highly thermal conductive products such as grease, gels, films, tapes, pads and coatings etc.
