Aluminum
NFE Series aluminum nitride powders (AlN) are polycrystalline, high-purity particles with a roundish shape, available in D50 sizes from 1.5 μm to 130 μm, with an epoxy-functional surface coating applied.
The roundish particle shape improves flowability and filling rate over fully irregular particles, offering a practical balance between thermal conductivity performance and cost. The coating improves particle bonding in epoxy resin matrices and raises hydrolysis resistance compared to uncoated grades. The wide size range, including grades from 1.5 μm, also makes NFE Series suitable as a sub-filler in ultra-thin thermal interface material formulations.
Key applications
NFE Series can be compounded with epoxy resins to develop highly thermally conductive products, including thermal adhesives, encapsulants, films, tapes, pads, and coatings.
