ANTIMONY TRIOXIDE

stars, based on 0reviews
items available

our range of Antimony trioxide is produced from stibnite ores (antimony trisulfide) or as a by-product 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 is used as a synergist to enhance the activity of halogenated flame-retardants by stepwise releasing the halogenated radicals to retard the gas phase chain reaction of flame spread.

FEATURES:

 

In flame retarding thermoplastics, the synergistic action between halogenated flame-retardants and antimony trioxide is well known in the plastic industry

 

The Izod impact strength and translucency are two key properties that are diminished because of the particle size and pigmentation strength of antimony trioxide

 

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


APPLICATIONS:

Flame retardant for wide range of plastics, rubbers, paper and textiles

Catalyst in PET production

Catalyst in PET production

Flocculant in Titanium Dioxide production

Paints and Adhesives industries

Pigments, Ceramic frites
