], Film containing calcium carbonate and barium sulfate. Molecular Formula. A small amount of copper sulfate is also needed to effectively remove cobalt from solution. n-propylnitrate. Alumina trihydrate (AI2O3•3H2O). In first stage solution purification, copper is removed by the addition of zinc dust. The use of antistatic agents such as quaternary ammonium compounds has been of some limited value in solving this problem. Antimony oxide is a white powder and is derived from the mineral stibnite (antimony sulfide) or produced by the oxidation of antimony metal or as a byproduct of the refining or antimonial-lead alloys. Since antimony oxide is insoluble in water, it has an added advantage over other flame retardants. Rotterdam per metric ton (a metric ton contains 2,204.6 pounds). Highly flexible and semi-rigid goods can be manufactured with these plasticizers. Antimony trioxide is an inorganic compound with the formula Sb 2 O 3. American Elements … Accelerators such as antimony oxide or arsenic oxide are used. At the same time, the action of zinc oxide is similar to that of antimony trioxide, but less effective. For example, with phosphorus chemistry, the behavior of manufactured or synthetic fibers cannot easily be compared to the performance of natural fibers and cotton, in particular. Oxide Weight: 291.60 Formula Weight: 291.60 Notes. High gloss film. Synonyms. [Data from Schramer, K. M.; Ocampo D. O., US Patent 4,223,054, Sep. 16, 1980. [Data from Grossman, R. F., J. Vinyl Additive Technol., 5, 1, 37-39, 1999. Antimonious oxide is widely used as a flame retardant for rubber and plastic materials. Antimony trioxide has been the oxide universally employed as flame retardant, but recently antimony pentoxide (Sb2O5) has also been used. There is no chemical formula for Antimony as it is a pure element and only contains atoms of Antimony. The viscosity of PVC pastes may be reduced in many instances by the presence of certain polyethylene glycol derivatives and related materials. [Data from Milan, S., US Patent 6,835,765, Dec. 28, 2004. S.V. George Wypych, in Handbook of Fillers (Fourth Edition), 2016. Phosphorus compounds in flame retardancy originated with ammonium phosphate on canvas in the 18th century, and the phosphorus flame retardants evolved with the advent of plastics into a wide range of inorganic and organic phosphorus additives and reactives. CAS Number 1314-60-9. Several chloroalkyl phosphate liquids continue to be the dominant additives in polyurethane foams. These systems perform as flame retardants but require a high filler concentration which affects jacket resistance and mechanical performance. It is the most important commercial compound of antimony. Commercial chemical fibers are combustible in nature, and improved FR properties must be considered in actual application. 1, 2008.]. Buy Silver Liquid Mercury in South Africa. It is found in nature as the minerals valentinite and senarmontite. An antimony compound and inorganic solid. Combination with zinc borate, zinc stannate and ammonium octamolybdate enhances the flame-retarding properties of antimony trioxide. Solution purification utilizes cementation in a three step process to remove harmful elements. EVA can be processed with flame retardants free of chlorine. By continuing you agree to the use of cookies. For some applications it is necessary that static charge should not accumulate on the product. ], Liquid thermal stabilizer having no toxicological impact. Antimonous oxide. The alternative stabilizing formulations are given in the tables below. The water of hydration in the compound rapidly splits off at temperatures higher than 300°C (upon burning), and the steam evolved obstructs the access of oxygen to the polymer, thus hindering the combustion process. Film (a new method of stabilization). These are based on magnesium hydroxide and aluminum hydroxide. Antimony oxides require the presence of a halogen compound to exert their fire-retardant effect. Triethyl phosphate is used in thermosets, while triaryl phosphates and alkyl diphenyl phosphates are used mainly in vinyls. Solution purification utilizes cementation in a three step process to remove harmful elements. Antimony (III) oxide, CP. Other systems include the mixture of huntite and hydromagnesite which offers relatively good performance. Antimony Tri Chloride. In the invented method, film from the calender directly enters a water bath tank which partially cools material and crystallizes it. Colloidal Mercury, Colloidal Silver Mercury, Colloidal Mercury, Mercury Colloidal Silver, Mercury Colloidal Gold, red cinnabar stone, red organic cinnabar, Buy Prime Virgin Silver liquid Mercury. Weil, in Advances in Fire Retardant Materials, 2008. Strengths and weaknesses of phosphorus flame retardants relative to other flame retardant systems (mostly halogen) can be summarized as following: Lower density compared with halogen types, Less likely to be persistent and bioaccumulative in the environment, Effective in promoting a char barrier in charrable polymers, Better photostability than most halogen types, Less tendency to intensify smoke obscuration, No halodioxin formation even on poor incineration of the plastics, More likelihood of biodegradability compared with halogens, Difficulty in making high %P compounds, so may be less efficient, Tendency to be hydrophilic and possibly cause moisture uptake, May hydrolyze to give acids which damage the plastic or spoil electrical properties, May be less thermally stable and thus limit processing temperature, Thermal and hydrolytic stability may impede recycling, Some toxicity questions related to reactivity. Because of their tendency to exude, the use of these viscosity depressants should be restricted to levels of less than 1% of the total mix. Some inorganic fillers are used as flame retardants in rubber base formulations. Chemical Formula: Sb2O3: CAS Number: 1309-64-4: Molecular Weight: 291.518: EC Number: 215-474-6: Specification: Purity: Available in 99.99%, 99.999%: Shape and particle size: Available in powder: Packaging : It is packed with Dacron film, then covered with a sealed plastic film bag.
