Product description
Nano alumina, A phase, 99.99% purity, white powder. It has stable crystal shape, high hardness and concentrated particle size distribution. It is widely used in coating, precision polishing, plastics, high performance ceramics, thermal conductivity, lithium battery and other industries.
Product Feature:
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
