Antimony Trioxide
Description: is made by antimony metal as raw material. It is white powder with wide range of applications. More than 80% of antimony trioxide is used as a flame retardant additive for various type of plastics, rubbers, and fiber. It is also used for polyester polymerization catalysts, variable resistors, decolorizing and fining of optical lenses, and as pigments.

Antimony Trioxide Dust Free
Description: Antimony trioxide dust free grade, a kind of product with special chemical treatment on the surface base on antimony trioxide powder. Dust free technique make the powder in slight wet condition. So, it can not only avoid human inhalation and touch possibility, but also can achieve the high efficiencyof flame retardancy and plasticing. It is very good protection for downstream factories worker and friendly to environment.
