More info

Antimony Oxide, also known as antimony white, is one of the inorganic flame retardants used early. It is an amphoteric oxygenate, applied in plastics, rubbers, chemical fibers, enamel, pigments, paints, glass, electronics, and other industries. HM also can provide high-purity (4N-5N) Antimony Oxide for semiconductor applications.
