Features: ● High filling property: high spheroidization rate and controllable particle size distribution, which can achieve high-density filling in silicone and epoxy systems to obtain precursors with low viscosity and high fluidity; ● High thermal conductivity: It can achieve multi-directional heat transfer, good dispersion in the system, and high thermal conductivity of thermal conductive products; ● Low wear: Because of its spherical appearance, it reduces wear on mixers, molding machines and other equipment, extending the life of the equipment.
Spherical alumina is calcined from ordinary irregular-shaped Al2O3 through high-temperature melt spraying, and then undergoes screening, purification and other processes to obtain the final product. Due to its unique properties such as high thermal conductivity and good fluidity, this product is widely used as thermal interface materials, thermally conductive engineering plastics and thermal fillers for aluminum-based copper-clad laminates.
● Thermal conductive engineering plastics: LED lampshades, switch casings, notebook casings, mobile phone casings, water tanks, motor coil skeletons, etc.;
● High thermal conductivity aluminum base copper clad laminate (AI Base CCL): high-power LED lighting, power circuits, LED TV, etc.;
● Alumina ceramic substrate surface spraying: potentiometer, chip resistor, etc.
