Spherical Alumina High Thermally Conductive series

Product Description:

Spherical alumina high thermally conductive series products is the deep processing products from BAK series through a series of special calcining, cleaning, screening and other processes, it not only can maintain the spheroidization rate, but also improve the content of α phase and reduce the specific surface area, so as to play a more powerfully thermal conductivity in the polymer matrix material.
