about

Aluminium Oxide

BORATHERM™ SA (spherical alumina) has been specially engineered from aluminium oxide to help skilled formulators maximise the heat dissipation properties of polymer composites, for example EV battery systems. 

Specially designed to offer an ultra-low surface area and large particle sizes, BORATHERM™ SG is perfectly suited for formulations needing good flowability. The specific gravity of grades is 2.4 g/cm
3
. 

Sibelco also offers Aluminium Oxide (Al
2
O
3
) which is an
artificial corundum
with an exceptionally high degree of hardness and a very tough grain. 

In collaboration with Momentive Technologies, Sibelco markets Spherical Alumina (SA) products for Thermal Interface Material (TIM) applications in Europe under a distributorship agreement. Sibelco will only be distributing SA products of Momentive in Europe under the Distribution Agreement.
