Products
This series comprises sodium antimonate (NaSbO3) and sodium pyroantimonate (Na2H2Sb2O7·H2O), cost-effective antimony-based flame-retardant synergists widely used in PVC, engineering plastics, rubber, textiles and composite materials. When combined with halogen-based flame retardants, sodium antimonate markedly raises the limiting-oxygen-index (LOI) and reduces heat-release rate, while improving processing flowability. Owing to finer particle size and superior dispersibility, sodium pyroantimonate fits high-end applications with stringent requirements on flame-retardant loading and finished-part appearance. We offer multiple grades from industrial- to high-purity. Key indicators including main-component content, whiteness, particle size, moisture and free-alkali can be tailored to requirements, accompanied by complete export documentation and stable supply arrangements.

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.
