Product feature:
There are several benefits to using 99.99% high alumina granulating powder, including:
Improved flowability: Granulated alumina powder flows more easily than fine alumina powder, which can improve its handling and processing characteristics.
Reduced dusting: Granulated alumina powder is less likely to dust than fine alumina powder, which can help to improve workplace safety and air quality.
Improved packing density: Granulated alumina powder can pack more densely than fine alumina powder, which can be beneficial in some applications.
Improved strength: Granulated alumina powder can be stronger than fine alumina powder, which can be beneficial in some applications.
Among the filling materials of thermal interface materials, 99.99% high alumina granulating powder is widely used to improve the handling and processing of alumina powder, which is a chemical compound made of aluminum oxide (Al2O3).
