Antimony Trioxide

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 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.

Applications

• Flame retardant for wide range of plastics, rubbers, paper and textiles
• Catalyst in PET production
• Activator in glass industry
• Flocculant in Titanium Dioxide production
• Paints and Adhesives industries
• Pigments, Ceramic frites

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

Other Details of flame retardant agent Flame Retardant are substances that can be chemically inserted into the polymer molecule or be physically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. There are several classes of flame retardants; Halogenated Hydrocarbons (Chlorine and Bromine containing Compounds and reactive flame retardants), Inorganic flame retardants ( Boron Compounds, Antimony oxides, Aluminium Hydroxide, molybdenum Compounds, zinc and magnesium oxides ), Phosphorous containing Compounds (Organic Phosphate Esters, Phosphates, halogenated phosphorus Compounds and inorganic phosphorus containing salts).
