Heat Conduction Material Al2O3 Fine Alumina Powder
Al2O3 Alumina powder has the advantages of thermal conductivity and insulation, and can be used as thermal conductivity filler to prepare thermal insulation adhesive, sealing adhesive 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. And the alumina price is lower, the source is wider, is economical suitable filler of the high thermal conductivity insulation polymer.
Hwnanomaterial can batch produce white alumina powder with narrow particle size distribution, stable process and high thermal conductivity coefficient. particle size in 1um, 500nm, 300nm, 200nm, etc. According to the customer's feedback, the thermal conductivity can reach 3-10w/(m*K) according to different filling quantity.
Heat-conducting alumina can be widely used in different materials such as silica gel, sealing adhesive, epoxy resin, plastic, heat-conducting rubber, heat-conducting plastic, silicone grease, heat-conducting ceramic and so on. In practical application, Al2O3 powder filler can be used alone or mixed with other fillers such as AIN and BN.
In order to provide dispersibility of alumina powder, the surface of alumina can be modified by silane coupling agent or hexadecyl trimethoxy silane.
