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
