Nanometer alumina for heat conduction

Selling Leads Detail

Company Info

 

Good hardness and stability. Widely used in plastic, coating, rubber, ceramic, refractory materials for improving toughness. It has effect of heat conducting in the plastic and rubber. Perfect performance in improving ceramic density, smoothness, the fracture toughness and creep resistance and wear resistance as well as keep temperature balance. It also be used in chemical fiber products and high pressure sodium as far-infrared emission and insulation material bacause of its excellent far-infrared emission ability. In addition, alpha alumina has high resistivity and good insulation performance, it can be applied to YGA laser crystal and integrated circuit substrate as main fittings. In the same filling quantity, nanometer alumina has better thermal conductivity and physical and mechanical properties than micron alumina in the electric rubber. In the proper proportions, the thermal effect of the thermal rubber that mixing nanometer alumina and micron alumina is better than only use microns of rubber filling particles. The alpha alumina 1000 mesh in mixing packing, when the weight fraction between 0.1 to 0.15, it has smallest viscosity, best liquidity and thermal conductivity. Used for thermal conductive filler in rubber and plastic, it not only improve thermal conductivity and insulation effect, but also improve the material mechanical properties . In silica gel, it has good thermal conductivity and transparency, but not effect the viscosity.
