Supply Hunan production of rubber and plastic products Gold antimony trioxide flame retardant market in the fourth quarter ..

Antimony white powder, insoluble in water, soluble in sodium hydroxide solution and acids. Properties: white crystalline powder. Heating yellow, after the cold white. Odorless. A melting point of 655 ℃. Boiling point of 1425 ℃. Heated to 400 ℃ can be sublimated at high vacuum. Soluble in sodium hydroxide solution, hot tartaric acid, tartaric acid and sodium sulfide solution, water-soluble acid. The relative density of 5.67. Preparation:? The stibnite (?? Sb S) Sb O ?, calcined oxide product was purified to remove arsenic and iron, and then to carbon reduction to metallic antimony smelting further purified and then oxidized in pure Sb O ?.? Uses: antimony trioxide catalyst used, mordant, fabric, paper, plastic flame retardants, glass decolorizing agent. For the preparation of antimony potassium tartrate, glazes and fire retardant. Manufacturing lead softener. Antimony trioxide is the first application of flame retardants used in rubber products, plastic products, epoxy, urethane, neoprene, polystyrene, polyvinyl chloride, polyester, etc., when used alone, the amount should be large, retardant effect is poor (except halogen-containing flame retardants), when compared with halogen compound (R.HX) and when you use a good synergy, flame-retardant effect significantly improved. Packaging: 25 kg / bag.
