Heat Conduction Materials
Spherical Alumina
●High Filling: High degree of spheroidization rate, controllable particle size distribution, achieve high density filling for silicone and epoxy resin, to get the mixture with low viscosity and high mobility;
● High Thermal Conductivity: Because of its almost perfect ball structure, the filler used in the raw materials can achieve multi-directional heat transmission.  The whole mixed system is in state of good dispersion, so final products have excellent thermal conductivity and physical property;
● Low Abrasion: Compared with irregular powder, the application of spherical filler can reduce the abrasion of the mixer, molding machines and other equipment, then prolong working life of relevant equipment
