Aluminum
SFS Series aluminum nitride powders (AlN) are polycrystalline, high-purity particles available in D50 sizes from 2 μm to 80 μm, with a silicone-compatible surface coating applied. The coating improves particle bonding in silicone polymer matrices and raises hydrolysis resistance compared to uncoated grades.
Key applications
SFS Series can be compounded with silicone polymers to develop highly thermally conductive products, including thermal grease, gels, films, tapes, pads, and coatings.
Features
Narrow particle size distribution
Silane-functional surface coating
