Flame Retardants Sodium Pyroantimonate Powder Industry Grade
Name: Sodium pyroantimonate
Molecular formula: NaSbO33H2O
Molecular weight: 246.75
Product character: sodium pyroantimonate is an inorganic salt compound of antimony. It is low toxic. It is produced with antimony oxide and other antimony products through alkali and hydrogen peroxide. The appearance is white powder, and there are two kinds of crystallized crystallized equiaxed crystals. The melting point is 1200 C, and the boiling point is 1400 C. Soluble in tartaric acid, sodium sulfide solution, concentrated sulfuric acid, slightly soluble in alcohol, ammonium salt, insoluble in acetic acid, dilute alkali and dilute inorganic acids, insoluble in cold water. The chemical stability is good.
Product category: inorganic salt
Product thumbnail: no!
Detailed description of the product:
Sodium pyroantimonate is mainly used in photovoltaic solar glass, black and white, color display display tube glass clarifier defoaming agent. Clarifying and defoamer for glass fiber, gem glass, high-grade glass, tableware and other high-grade glass, and widely used in electronic manufacturing, engineering thermoplastics, rubber fire retardant, such as flame retardant electronic equipment shell, flame retardant compartment, flame retardant wire. It is also used as a flame retardant for textiles, plastics, building materials and so on.
It has been widely used as a flame retardant to replace antimony oxide in the world. It has been proved by scientific experiments and production that it has more excellent technical performance. For all the polymers, has excellent flame retardancy, for unsaturated polyester and engineering thermoplastic plastic is lower in light resistance and lower tinting strength, it has the characteristics of low reaction performance, this is the sensitive polymer (such as PET) one of the advantages of the antimony oxide flame retardant used in in the process of operation is easy to cause depolymerization.
Packaging: inner plastic 25KG/ bag 50KG/ bag 500KG/ bag 1000KG/ bag
