Spherical alumina(D10>35)

Product Name Spherical alumina(D10>35) Product Overview Spherical alumina is a high-performance inorganic powder material prepared from high-purity alumina raw materials through high-temperature melting injection, spheroidization, precise screening and purification modification processes. It features high sphericity, uniform particle size distribution, high purity, excellent thermal conductivity, fluidity, insulation and chemical stability. With low impurity content and compact structure, it is widely used as a core functional filler for high-end thermal conduction, filling and wear-resistant composite materials. Product Features 1. Ultra-high thermal conductivity: The thermal conductivity reaches 20–30 W/m·K, which can build stable 3D thermal conduction channels in resin systems and significantly improve heat dissipation efficiency. 2. Excellent fluidity and low viscosity: The spherical particle structure has low friction and compact stacking with low oil absorption value, supporting high filling ratio, reducing composite viscosity and adapting to precision processing. 3. Low wear and high compatibility: Round and non-angular particles cause minimal wear to production equipment, extend service life, and fit for various mixing, coating and molding processes. 4. High purity and stability: Purity over 99.6% with low ionic impurities, excellent insulation, acid and alkali resistance, high temperature resistance and anti-oxidation performance. 5. Customizable particle size: Multiple particle size specifications with concentrated distribution and high batch consistency for refined application scenarios. Application Fields 1. Thermal interface materials: Thermal grease, thermal pads, thermal potting glue, phase change thermal materials, thermal double-sided adhesive. 2. Thermal conductive engineering plastics: LED heat-dissipating plastics, electronic casings, new energy vehicle insulating and heat-dissipating components. 3. Electronic packaging materials: Chip packaging, copper-clad laminates, insulating filling for electronic components. 4. Functional coating materials: Thermal conductive anti-corrosion coatings, wear-resistant and high-temperature resistant coatings. 5. Precision ceramics and polishing: High-end ceramic substrates, precision polishing fillers, catalyst carriers. 6. Other fields: Insulating composite materials, special rubber, adsorption and filtration materials.
