What is Sodium Pyroantimonate used for?

The following is a marketing copy optimized for Sodium Pyroantimonate, highlighting its technical differentiation and industry application value:
 
Sodium Pyroantimonate: A new generation of high-performance flame retardants and glass clarification solutions
As the core representative of pentavalent antimony compounds, Sodium Pyroantimonate has become an irreplaceable green additive in the field of high-end manufacturing due to its unique chemical stability and functionality:
 
 1. Core technology for high-end glass manufacturing
- Photovoltaic glass super-transparent engine: As a special clarifier for ultra-white glass of photovoltaic panels, it effectively eliminates microbubbles, increases light transmittance ≥ 0.5%, and directly increases the power generation efficiency of components
- Display Industry Color Master: Precisely control the refractive index in CRT/LED display glass to ensure color purity and simultaneously achieve defoaming-clarification-color stabilization triple functions
- Gem-level processing guarantee: Used for artificial gem glass melting, suppresses lattice defects, and achieves VVS-level clarity standards
 
 2. Revolutionary flame retardant technology upgrade (compared with traditional antimony oxide)
Performance Dimension Advantages of Sodium Pyroantimonate Industrial Value
Flame retardant efficiency Synergistic flame retardant effect increased by 40% Reduced by 30% to achieve UL94 V-0 grade
Material compatibility Nearly zero depolymerization reaction Guarantee the integrity of sensitive polymer chains such as PET
Optical influence Transmittance > 99% / Coloring power decreased by 65% Maintain the original color of engineering plastics
Thermal stability Decomposition temperature > 550℃ Adapt to high temperature injection molding/extrusion process
 
 
Core application scenarios:
✅ Flame retardant shell of the new energy battery pack
✅ 5G base station engineering plastic parts
✅ Ship-grade flame-retardant cable sheath
✅ Fireproof coating of military building materials
 
 3. Irreplaceability in special scenarios
- Chemical passivation characteristics: No side reactions occur in halogen-containing flame retardant systems, avoiding equipment corrosion caused by traditional Sb₂O₃
- Color customization capability: As a sodium antimony oxide complex, it meets the color rendering requirements of special ceramics/glazes cobalt blue-titanium yellow series
- Compliance advantages: Passed RoHS 3.0 certification and complies with the harmless electronic and electrical product directive
 
Empirical case
▶ After a TOP5 photovoltaic glass factory adopted it, the yield rate increased by 2.1%, saving $2.3M annually
▶ PET connector application solution for an automotive electronics company, passed the 1500h wet heat aging test with zero performance degradation
 
As a globally scarce pentavalent antimony technology carrier, we provide full-cycle services from molecular structure design to application scenario verification to help customers break through material limits. 
 
> Technical Note: According to the IPCS International Chemical Safety Card, the low mobility of sodium pyroantimonate (NaSbO₃) in polymer systems significantly reduces the risk of occupational exposure.
