Product Overview
Key Features
Antimony Trioxide
Antimony trioxide is an inorganic compound with the formula Sb2O3, CAS No.1309-64-4. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions only with hydrolysis.
The main application is for flame retardants in combination with halogenated materials. The combination of the halides and the antimony being key to the flame-retardant action for polymers, helping to form less flammable chars. Such flame retardants are applied majorly in cables, plastics, electrical apparatus, leather and coatings.
Other applications:
- Antimony trioxide is a useful polycondensation catalyst in the production of polyethylene terephthalate (PET plastic)
- It is also an effective catalyst for textiles (yarns).
- Antimony trioxide is a useful catalyst in the vulcanization of rubber.
- Some specialty pigments contain antimony.
- Flame retardant for textiles, leather, polymers, and coatings
- Antimony trioxide is an opacifying agent for glasses, ceramics and enamels.
