Silicon Carbide Powders

Silicon Carbide Powders - SIKA ABR IV A - Industrial grade black silicon carbide Levigated Alumina (Grain Code 7930) - Levigated Alumina is a 98% pure high-quality calcined alumina that is air classified to achieve a tightly-sized distribution. Levigated Alumina is recommended as a direct substitute for other electrically-resistant white fillers where high hardness andor high thermal conductivity is desired. A very important feature of all aluminas is their inherent combination of desirable electrical and thermal properties.
