Derived through specialized calcining, cleaning, screening, and other processes from the SSAC series, Spherical Alumina Powder (High Thermally Conductive) represents a deep-processed product. These processes not only uphold the spheroidization rate but also enhance the α phase content while reducing the specific surface area. Consequently, High Thermally Conductive Spherical Alumina Powder significantly boosts thermal conductivity within polymer matrix materials.
