Products

This series focuses on antimony-based flame-retardant functional materials, covering four product grades: colloidal antimony pentoxide, antimony pentoxide powder, sodium antimonate and sodium pyroantimonate. They find broad application in flame-retardant plastics, engineering resins, textile coatings, rubber and composite materials. The comparison below outlines core characteristics, typical applications and key selection indicators to support procurement decisions.

Product Form	Key Characteristics	Typical Applications	Critical Selection Parameters
Colloidal antimony pentoxide	Nanoscale dispersed particles; high synergistic efficiency with halogen-based flame retardants at low loading levels	High-end flame-retardant coatings, thin films, fine-denier fibres	Solids content, pH value, colloidal particle size (D50), viscosity and system compatibility
Antimony pentoxide powder	High-purity oxide powder; self-dispersible or amenable to further processing	Engineering plastics, rubber, flame-retardant masterbatches	Purity (Sb₂O₅ ), particle-size distribution (D50), whiteness and impurity control
Sodium antimonate / Sodium pyroantimonate	Inorganic antimonate salts with outstanding thermal stability and good compatibility with multiple polymers	Polyester, engineering plastics, glass-ceramic flame-retardant systems	Main-component content, free alkali / free acid, moisture content and bulk density

We assist customers in identifying the optimal product grade according to their formulation and processing conditions (e.g. extrusion temperature, dispersion method, carrier resin). Samples and basic formulation suggestions are offered to minimise trial-and-error costs.

Sodium Pyroantimonate (C5H4Na3O6Sb) Sb2O5 Assay 64%~65.6% be used as flame retardant

Sodium Pyroantimonate is an inorganic salt compound of antimony, which is produced from antimony products such as antimony oxide through alkali and hydrogen peroxide. There are granular crystal and equiaxed crystal. It has good chemical stability.
Sodium Antimonate (NaSbO3) Cas 15432-85-6 Sb2O5 Assay Min.82.4%

Sodium Antimonate (NaSbO3) is a kind of inorganic salt, and also called sodium metaantimonate. White powder with granular and equiaxed crystals. High temperature resistance, still does not decompose at 1000 ℃. Insoluble in cold water, hydrolyzed in hot water to form colloid.
Antimony Pentoxide colloidal Sb2O5 widely used as flame retardant additive

Colloidal Antimony Pentoxide is made through a simple method based on reflux oxidization system. UrbanMines has detailedly investigated about the effects of experimental parameters on the colloid stability and size distribution of the final products are carried out. We specialize in offering colloidal antimony pentoxide in a wide range of grades developed for specific applications. The particle size ranges from 0.01-0.03nm up to 5nm.
Barium Acetate 99.5% Cas 543-80-6

Barium acetate is the salt of barium(II) and acetic acid with a chemical formula Ba(C2H3O2)2. It is a white powder that is highly soluble in water, and decomposes to Barium oxide on heating. Barium acetate has a role as a mordant and a catalyst. Acetates are excellent precursors for production of ultra high purity compounds, catalysts, and nanoscale materials.
Excellent Quality Antimony Pentoxide Powder at Reasonable Price Guaranteed

Antimony Pentoxide (molecular formula: Sb2O5) is yellowish powder with cubic crystals, a chemical compound of antimony and oxygen. It always occurs in hydrated form, Sb2O5·nH2O. Antimony(V) Oxide or Antimony Pentoxide is a highly insoluble thermally stable Antimony source. It is used as a Flame retardant in clothing and suitable for glass, optic and ceramic applications.
