AW Series aluminum nitride powders (AlN) are polycrystalline, high-purity particles available in D50 sizes from 2 μm to 80 μm, with an advanced anti-hydrolysis treatment applied.
The anti-hydrolysis treatment provides excellent hydrolysis resistance, helping maintain thermal performance and powder stability in wet and humid conditions. Hydrolysis resistance is tested with the powder immersed in water at 85°C/85%RH for more than 500 hours.
Key applications
AW Series can be compounded with silicone polymers and epoxy resins to develop highly thermally conductive products, including grease, gels, films, tapes, pads, and coatings.
