Engineered for excellence, trusted by global industry leaders.
Spherical Alumina Powder (Al₂O₃) is a high-performance ceramic material characterized by its high sphericity, narrow particle size distribution, and exceptional thermal conductivity. Unlike angular alumina, the spherical morphology allows for higher filler loading in polymers, significantly reducing viscosity and improving the thermal interface properties of the final product.
In the era of 5G, New Energy Vehicles (NEV), and AI computing, electronic components are becoming smaller and more powerful. This generates immense heat. Our spherical alumina acts as the critical thermal filler in Thermal Interface Materials (TIMs), heat sinks, and potting compounds, ensuring longevity and reliability of high-end electronics.
As a leading supplier, Shanghai Creative Advanced Materials Co., Ltd (SCA) bridges the gap between raw material purity and high-tech application requirements. We provide a stable supply chain for Fortune 500 companies in the semiconductor and aerospace sectors.
