Antimony Trioxide Antimony trioxide, also known as antimony oxide or Sb2O3, is the most widely produced com-pound of elemental anti-mony. The nations that produce the most antimo-ny trioxide are China, South Africa, Bolivia, Russia, Tajikistan, and Kyrgyzstan. Typical applications for antimony trioxide include flame retardant synergist for

Antimony oxide by itself is not a fire retardant, and the halogens by themselves, mainly bromine and chlorine, are weak fire retardants. However, when they are combined they become synergistic and are the most effective and most widely used flame retardant system for plastics. ... Two mechanisms exist in the synergistic system.
The use of Diantimony Trioxide as catalyst for the polymerization of PET resin was deemed safe by the European Food Safety Administration (EFSA), with a migration limit established at 0.04 mg/kg of food (as Antimony) (allowing for 10% of the Tolerated Daily Intake (TDI) being allocated to food contact materials.
Antimony oxides (primarily antimony trioxide) are used as fire retardants for plastics, textiles, rubber, adhesives, pigments, and paper. (1) Sources and Potential Exposure Antimony is found at very low levels throughout the environment. (1) The concentration of antimony in ambient air ranges from less than 1 nanogram per cubic meter (ng/m 3)
Apr 02, 2013· Antimony trioxide (Sb 2 O 3) is used in the manufacture of PET as a catalyst. It has been shown to migrate from PET and migration is enhanced at higher temperatures and lower pH (corresponding to higher acidity). The toxicity of Sb is not fully established yet.

Antimony trioxide is a white crystalline solid. It is insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used to fireproof fabrics, paper and plastics, as a paint pigment and for many other uses.
Antimony trioxide has been used as a white pigment since ancient times. The pigmentation from antimony oxide in plastics can be controlled and adjusted by the judicious selection of a Sb 2 O 3 grade having a specific particle size. The product with the smallest particle size and the narrowest particle-size range imparts the whitest color and highest opacity.
Paints - Paints can be made flame retardant by providing a halogen, usually chlorinated paraffin or rubber, and 10% to 25% antimony trioxide. Additionally antimony oxide is used as a color "fastener" in paint subject to ultraviolet radiation that tends to deteriorate colors.
Antimony trioxide is used in the manufacturing of polyethylene terephthalate (PET), a food contact plastic used extensively for single-use water and beverage bottles and food trays. Both storage time and high temperatures are factors that increase the migration of antimony from the food contact plastics to the food or beverage.
Antimony(III) oxide has suspected carcinogenic potential for humans. Its TLV is 0.5 mg/m 3, as for most antimony compounds. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.
OCCURRENCE AND USE. Antimony trioxide is formed by reacting antimony trichloride (SbCl 3) with water.It is used in combination with some brominated flame retardants, and might also be used in conjunction with zinc borate, both within and outside the United States on commercial furniture, draperies, wall coverings, and carpets (R.C.Kidder, Flame Retardant Chemical Association, unpublished ...
Antimony Trioxide Availability. It is found in nature as the minerals Valentinite and Senarmontite. Many commercial manufacturers produce Antimony Trioxide using stibnite ores (Antimony Trisulfide) or as a by-product of lead smelting. Antimony Trioxide can also be produced using Antimony Trichloride, which is derived from Stibnite.
