Our range of Antimony trioxide is produced from stibnite ores (antimony trisulfide) or as a byproduct of lead smelting and production. Antimony Trioxide is used mainly in fire retardant formulations for plastics, rubbers, textiles, paper and paints. Further, Antimony Trioxide can be used as an additive in glass and ceramic products and as a catalyst in the chemical industry. Occupational exposure may occur during mining, processing and smelting of antimony ores, in glass and ceramics production, and during the manufacture and use of products containing antimony trioxide. Antimony trioxide and pentoxide do not react as flame-retardants directly. Antimony Trioxide are used as synergists to enhance the activity of halogenated flame-retardants by stepwise releasing the halogenated radicals to retard gas phase chain reaction of flame spread.

Common Applications

1. Flame Retardant: One of the primary applications of antimony trioxide is as a flame retardant. It acts as a synergist with other flame retardant chemicals by inhibiting the combustion process and reducing the flammability of various materials, including plastics, textiles, and rubber.
2. Polymer Additive: Antimony trioxide is commonly used as a polymer additive in the production of plastics and rubber products. It enhances the fire resistance of these materials and improves their overall performance.
3. Catalyst: Due to its catalytic properties, antimony trioxide is utilized in the production of polyester fibers, polyethylene terephthalate (PET) resins, and other chemical processes.
4. Glass Industry: Antimony trioxide is added to glass formulations to improve its clarity and brilliance. It acts as a fining agent, removing small air bubbles and impurities during the glass melting process.
5. Pigment and Paints: In some cases, antimony trioxide is used as a white pigment in paints and coatings, providing opacity and brightness.
 
Features
1. In flame retarding thermoplastics, the synergistic action between halogenated flame-retardants and antimony trioxide is well known in the plastic industry
2. The Izod impact strength and translucency are two key properties that are diminished because of the particle size and pigmentation strength of antimony trioxide
3. The loss in translucency limits the range of available color choices because of the high loading required to offset the tinting effect of antimony trioxide
