Calcined Alumina (FA) Series for Heat Conduction

Alumina has the advantages of heat conduction and insulation, and can be used as a thermally conductive filler for the preparation of thermally conductive insulating glue, potting glue and other polymer materials.

Thermally conductive alumina is a white powder crystal generated under high temperature conditions. There are many crystalline powders. The alumina used for thermal conductivity includes spherical alumina, quasi-spherical alumina, and composite alumina.

Features

1. Reasonable particle size distribution, high filling rate, low viscosity and good fluidity mixture can be obtained

2. High thermal conductivity, compared with crystalline silicon, the thermal conductivity of the mixture is high

3. Low abrasion rate: the appearance is spherical, and the abrasion of the mixer and the forming mold is small

4. The content of sodium and chlorine ion-like impurities is very small, and it has good electrical moisture resistance
