Antimony is used in the manufacturing of products such as textiles and plastics for its flame retardant properties, as a catalyst, a pigment, to improve the properties of friction materials, and as a de-foaming agent in the production of glass. Molecular Weight: 291.5. Sb2O3 is used as a fire retardant in rubber, plastics, wire & cable and other composites. tin tin oxide zinc hydroxystannate zinc stannate organotin compounds antimony trioxide alumina trihydrate magnesium hydroxide titanium dioxide molybdenum trioxide iron oxide zinc borate alumina halogenated flame retardants metal halides thermal analysis Mössbauer spectroscopy fire-retardant mechanism ultrafine powders coated fillers Like most polymeric oxides, Sb 2 O 3 dissolves in aqueous solutions with hydrolysis.A mixed arsenic-antimony oxide occurs in the nature as the very rare mineral stibioclaudetite. It is found that the inorganic reinforcement minerals improved the flame retardant properties and thermal stability of polymer nanocomposites depending on the amount of additives. Ji Su Kim Human Convergence Technology R&D Department, KITECH, Ansan 15588, Korea. Flame-Retardant Mechanism and Mechanical Properties of Wet-Spun Poly(acrylonitrile-co-vinylidene chloride) Fibers with Antimony Trioxide and Zinc Hydroxystannate by Ji Su Kim Antimony trioxide itself has no flame retardant function, however, when it is used together with halogenated compounds, the synergistic effect of the mixture creates the flame retardant properties. It is not absolutely necessary but makes the system more cost effective Alternatives to ATO are sought due to: The antimony oxide reacts with the halogen containing compound forming highly volatile antimony oxychloride (Touval, 1993). Furthermore, the reports on the effect of the synergistic flame retardant such as antimony trioxide on the flame retardancy of bisphenol A epoxy resin are few in the open literature [9] [10][11]. A number of chemicals that have been used either as flame retardants, or to enhance the flame-retardant properties of other chemicals, are on the Proposition 65 list. Flame retardant specifications; There are two flame retardant mechanisms associated with this synergistic system. Antimony Trioxide Antimony trioxide is used mainly in fire-retardant formulations for plastics ( PVC resin, Vinyl resin and other resins compatible to DOP ), rubbers, textiles, paper and paints. More Information; Description: Sb2O3 Antimony Trioxide is an inorganic compound predominantly utilized as a flame-retardant synergist for plastics, paints, rubber, electronics, and textiles. Consequently, the total plastic composition must be considered in developing a new flame retardant product. However, when you combine it with halogenated materials (primarily bromine and chlorine), it can be used as a flame retardant synergist in a range of industries. 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. It acts also as a smoke suppressant in various systems [150]. 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. Medicinally it, in the form of a mixture ( milk of magnesia ), is also used as an antacid and as a osmotic laxative. Abstract A number of halogenated flame retardants have been heated alone and with antimony trioxide at temperatures between 300 and 500°. ... interfere with the flame retardant mechanism. The most used flame-retardant agent is antimony trioxide. However, when they are combined they become synergistic and are the most effective and most widely used flame retardant system for plastics. Flame retardant mechanism : Flame Retardant Mechanism of play through a number of flame retardant, such as the endothermic effect, cover effect, inhibition of chain reaction, the role of non-combustible gas asphyxiation. There are several classes of flame retardants; Non-halogenated / Halogen-FREE (Ammonium Polyphosphate, Melamine Polyphosphate etc) 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 phosphorous compounds and inorganic phosphorus containing salts ). The exothermic processes, which occur in the flame, are thus stopped, the system cools down, the supply of flammable gases … Yamanaka Sangyo began the smelting of antimony in Japan in 1900. Antimony trioxide dissolves in aqueous solutions only with hydrolysis. Expanded Antimony Applications, Antimony-Supporting High Quality of Your Products. Zinc Borate Zinc Borate is used as a flame retardant and smoke suppressant for a wide range of plastics, rubber, paper and textiles. Flame Retardant Mechanism of Antimony Trioxide Antimony trioxide itself has no flame retardant function, however, when it is used together with halogenated compounds, the synergistic effect of the mixture creates the flame retardant properties. Halogen based systems work in the gas phase. The above reactions are considered to be as follow; ＊Br content, including 50-70% TBA derivative and Oligomer type. It is used in the refining of sugar, in extraction of magnesium metal, in the processing of uranium, and in the sulfite wood pulp process. Antimony trioxide can leach into food and beverages from some containers made with antimony trioxide that are exposed to high temperatures (especially above 110 °F). Product Name: antimony trioxide. 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. The wide spread use of the fire retardant antimony trioxide (Sb2O3) on building materials and furnishings makes it inevitable that mold growth on treated materials will occur in some buildings with water damage. The mechanism works in the vapor phase by capturing the free radicals generated by the combustion process. , including 50-70 % TBA derivative and Oligomer type, paints,,.
