SPHERICAL ALUMINA POWDER ADVANTAGES
Perfect Spherical Shape: Improves flowability and dispersibility in resin systems
High Thermal Conductivity: Typically 20–30 W/m·K (depending on formulation)
High Chemical Purity: Stable under harsh processing conditions
Excellent Insulation: Electrically insulating yet thermally conductive
Low Oil Absorption: Allows high loading in polymer matrices without excessive viscosity
Uniform Particle Size: Reduces agglomeration and enhances composite performance
