Application of thermal conductive alumina:

Al2O3 alumina powder has the advantages of thermal conductivity and insulation, and can be used as a thermally conductive filler to prepare thermal insulation glue, sealant and other polymer materials. Compared with other fillers, although the thermal conductivity of alumina is not the best, it can meet the basic thermal conductivity requirements. Moreover, alumina has a low price and a wide range of sources. It is an economical and suitable filler for high thermal conductivity insulating polymers.

Thermally conductive alumina can be widely used in different materials such as silica gel, sealant, epoxy resin, plastic, thermally conductive rubber, thermally conductive plastic, silicone grease, thermally conductive ceramic and so on. In practical applications, Al2O3 powder filler can be used alone or mixed with other fillers such as AIN and BN.


In order to provide the dispersibility of the alumina powder, the surface of the alumina can be modified by a silane coupling agent or cetyl trimethoxysilane.
