Activated magnesium oxide is a kind of chemical raw material with chemical activity and physical adsorption capacity. It also has good sintering performance. It can be sintered at low temperature without using sintering aids. It is often added to various materials as flame retardant. The micro-morphology of active magnesium oxide is irregular particles or near-spherical particles or flake crystals, which is different from some indexes of ordinary magnesium oxide.

Activated magnesium oxide is used in fluorine rubber, chloroprene rubber, butyl rubber, chlorinated polyethylene (CPE), polyvinyl chloride (PVC) plastics and adhesives, inks, paints, etc. It can be used in rubber-sheathed cable, mine cable, marine cable and other industries. It can improve the anti-corrosion, acid resistance and high temperature resistance of cables, and improve the stability of cables in harsh environment.
