Compared with the traditional thermallyeonduetive plastics,thermally conductive engineering-plastics have both the excellent thermal conductivity and the excellent mechanical properties. Besides, they also have many other excellent properties,such as weatherability, corrosion resistance and so on, which makes them achieved widely application in many industrial fields including electrical and electronic industry,heating/cooling fields. The categories and composition of thermally conductive engineering-plastics were reviewed,and the type and characteristic of thermal conductive fillers were compared ;the corresponding heat-conduction mechanism of both insulated and noninsulatedthermally conductive plastics was also analyzed, the effects of the type, content, shape and compound of thermal conductive filler on the thermal conductivity of filled conductive plastics was discussed. And then the recent research development of thermally conductive engineering-plastics were introduced ; Besides, the application of filled conductive plastics on LED lamps,heat-exchange equipment,mieroeleetronies and other areas were introduced,and the market prospect of thermally conductive engineering-plastics was prospected.
