Applications:
- The major use of Antimony Oxide is as a Flame Retardant synergist in plastics, rubber, textiles, adhesives, fiberglass & Paper.
- Glass manufacturers use it as a fining agent or as degasser (to remove bubbles).
- Porcelain and Enameling services use it as an opacifier.
- Paint manufacturers use Antimony Oxide as a white pigment. It is sometimes used with other materials to form yellow pigments.
