Antimony trioxide is mainly used as a chemical synergist in chlorinated and brominated flame-retardants, increasing the retardants’ effectiveness. Antimony trioxide is a known flame retardant for use in plastics, ceramics and the like. [3] Antimony trioxide is produced when elemental antimony is heated and/or oxidized. South Africa, Russia and Bolivia produce lesser amounts. Flame retardants containing antimony trioxide are used widely in producing textiles, plastics, rubber, and paints. Antimony is a regulated contaminant that poses both acute and chronic health effects in drinking water. The product with the smallest particle size and the narrowest particle-size range imparts the whitest color and highest opacity. Many industries use antimony as a flame retardant synergist including but not limited to the plastics, textiles, rubber, paper, and paint industries. [37], Antimony metal increases hardness and strength in lead alloys and is used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, and pewter. More Information; Description: Sb2O3 Antimony Trioxide is an inorganic compound predominantly utilized as a flame-retardant synergist for plastics, paints, rubber, electronics, and textiles. Agency for Toxic Substances and Disease Registry (ATSDR). Antimony oxide is a white crystalline powder so as a result it can be used as a white pigment for paint; it is sometimes used with other materials to form yellow pigments. Antimony Trioxide can be used as an additive in glass and ceramic products and as a catalyst in the chemical industry. [3], Canadian market demands for antimony trioxide are met through imports. Antimony pentoxide particle occupies only 0.2% of the cross-sectional area of fiber vs. 7% for antimony trioxide. 1986/164, Guidelines for Canadian Drinking Water Quality, Ontario Drinking Water Quality Standards, O Reg 169/03, Contaminated Sites Regulation B.C. Antimony trioxide (Sb2O3) is a slightly soluble, white crystalline powder. The Oeko-Institut has recommended against a restriction of antimony trioxide (ATO) in electrical and electronic equipment under the EU’s Restriction of Hazardous Substances (RoHS) directive. ... solutions have been specially developed to meet both performance requirements and legal standards in every sector where plastics or textiles are used. For more information, see the occupational exposure estimate for antimony trioxide. Search for exhibitors & products. It is also used as a catalyst to produce polyester, and is found in plastics used for disposable beverage bottles. 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. Antimony Trioxide (ATO) provides unique properties not easily obtained through other products when applied in a variety of industrial processes. The provided antimony trioxide is tested by our quality experts at our labs so as to ensure its purity. Sign up for one or both of these newsletters below. Antimony Trioxide (Sb 2 O 3) is used as a synergist to halogen based flame retardants. Antimony oxide can be prepared by two processes, the direct and the indirect process. Royal Chemicals (India) - Offering Powder Antimony Trioxide, Packaging Type: 25 KG BAGS at Rs 200/kilogram in Mumbai, Maharashtra. Health hazard. Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3.It is the most important commercial compound of antimony.It is found in nature as the minerals valentinite and senarmontite. [37] Most of the market for antimony trioxide is in flame retardants for use in vinyl fabrics, wire & cable, and other plastics and rubber. Reg. Many industries use antimony as a flame retardant synergist including but not limited to the plastics, textiles, rubber, paper, and paint industries. [36] As of 1995, antimony trioxide gained popularity as an additive in optical glass, replacing arsenious oxide. If the color of antimony trioxide is improver to white and its particle size is smaller , the quality is regarded as superior. Offered antimony trioxide is used mainly in fire retardant formulations for plastics. Krachler M, Zheng J, Koerner R, Zdanowicz C, Fisher D, Shotyk W. Because technology is currently unavailable for the recovery of Sb from plastics, the metalloid is widely dispersed in products derived … Antimony Trioxide is generally used as flame retardant synergies in various material like rubber, textiles, plastics, and adhesives. Increasing Fire Safety Ensuring high levels of fire safety. Low addition levels of ATO effectively reduce the overall dosage of the Flame Retardant additives thereby reducing the deterioration of the physical properties of the plastics. The vapors are quenched with air and cooled to convert the vapor to white powder. [3] Digestive and neurologic symptoms have been reported from high levels of exposure, but causal relationships have not been established. People are mainly exposed to antimony trioxide in the workplace. 215-175-0. [38] Canada produces a very small fraction (0.1%) of global antimony metal. Many specialty glass companies use antimony trioxide for this purpose. [1] Antimony trioxide is a respiratory carcinogen in female rats. These flame retardant plastics are chiefly used in electronics applications. Our offered antimony trioxide is formulated by skilled professionals using quality chemical compounds and modern technology in observance with industry norms. In terms of occupations, the largest exposed groups are police officers (exposed in firing ranges) and welders. These powders are further filtered to give antimony trioxide powder. [38], The main source of exposure to antimony trioxide for the general population is through dermal contact with household items that contain flame retardants, such as paint, mattress covers and furniture upholstery. [42], Other sources of environmental exposure include food, drinking water, and air. The vapors are then condensed to convert the vapor to white powder. [4] There are numerous other synonyms and product names; see the Hazardous Substances Data Bank (HSDB) for more information. Offered range is properly tested by the quality analyzer to ensure it quality. In fact, positive results have been obtained for TV and PC screen plastics … Antimony trioxide does not react as flame-retardants directly. [35] It is also used as a pigment and/or clarifying agent in certain glasses and ceramics. [3] An early study reported that exposure is associated with an increase in spontaneous abortions, premature birth, and slow growth rates in offspring. Depending on the types of plastics , antimony trioxide for flame retardant application is admixed in an appropriate ratio with halogen series flame retardant to enhance its flame retardant. [35] Flame retardants containing antimony trioxide are used widely in producing textiles, plastics, rubber, and paints. [4], Antimony trioxide was last classified by the International Agency for Research on Cancer (IARC) in 1989 as Group 2B, possibly carcinogenic to humans, based on inadequate evidence in humans and sufficient evidence in animals. Antimony trioxide is the main catalyst used to produce polyethylene terephthalate (PET) and polyester fibers. PET is one of the best materials for plastic bottles, with a history of safe use by millions of consumers every day. Antimony trioxide is used as an opacifier for porcelain and enamel and a white pigment for paint. These antimony trioxide plastic are 95% pure and ideal for various industries.
