Performance of Spherical quartz powder Spherical SiO2：
1. High sphericity, uniform size, can be added to a large extent, the viscosity of the polymer system does not change significantly;
2. The surface of spherical silicon oxide has good fluidity, uniform film formation by stirring with resin, small amount of resin added, good fluidity and high powder filling amount. The smaller the thermal expansion coefficient and the lower the thermal conductivity, the closer it is to the thermal expansion coefficient of single crystal silicon, and the better the performance of the electronic components produced therefrom;
3. When the spherical silicon oxide filled plastic encapsulates the integrated circuit chip, the yield is high, the friction coefficient of the spherical silicon oxide powder is small, and the wear of the mold is small, so that the service life of the mold is long. Compared with the angle powder, the mold can be improved. Double the service life;
