SUBGLOBULAR ALUMINA POWDER FOR HIGH THERMAIL CONDUCTIVE MATERIAL

 

                             

 

This product is a subglobular alumina powder with green density, good dispersity and good interface compatibility with organic polymer material. It meets the requirement of high filler content. The particle size distribution is narrow and the product is with high purity, good heat conductivity and insulation. Besides the normal products, we also provide products subject to customers’ needs of average particle size covering from 1-3μm 、5-7μm、10-12μm, and 20-25μm high thermal conductivity spherical alumina.


Applications:


This product is mainly applied to high polymer materials of organic silicon-based and epoxy, and used in thermal conductive pad, heat conductive silicone grease, potting compound and electrical packaging. It also can be a substitution of the imported like products.
