- Antimony Oxide Powder Primary End Use:
a) The main application is for flame retardants in combination with halogenated materials. The combination of the halides and the antimony being key to the frame-retardant action for polymers, helping to form less flammable chars. Such flame retardants are found in electrical apparatus, textiles, and coatings.
b) Other applications:
1) Antimony trioxide is an opacifying agent for glasses, ceramics and enamels.
2) Some specialty pigments contain antimony.
3) Antimony trioxide is a useful catalyst in the production of polyethylene terephthalate (PET plastic) and the vulcanization of rubber.
