Antimony Trioxide
High-Performance Flame Retardant & Catalyst for Polyester Production
Antimony Trioxide is a white crystalline powder widely used in flame-retardant systems, polyester production, and glass & enamel manufacturing. With high purity and consistent Sb₂O₃ content, it plays a critical role in thermal stability, catalysis, and opacity control.
Product Overview
Antimony Trioxide (Sb₂O₃) is one of the most commonly used antimony compounds in the world. It acts as a synergist in halogenated flame-retardant systems and as a catalyst in the production of PET (polyethylene terephthalate) resins.
Its high whiteness and stability also make it useful in ceramics, glass, and coating applications, where it helps improve opacity, whiteness, and UV resistance.
Key Features
High Flame Retardant Efficiency when combined with halogen systems.
Excellent Dispersibility in polymer matrices and PET systems.
High Purity (≥99.8%) for sensitive applications.
Thermal Stability up to 600°C.
Multi-industry Versatility including textiles, electronics, glass, and plastic.
Applications
Flame Retardants
Acts as a synergist in halogen-based FR systems for plastics, rubber, textiles, and electronics.
PET Catalyst
Promotes esterification and polycondensation reactions in polyester fiber, film, and bottle-grade resins.
Glass and Ceramics
Functions as a clarifier and opacifier, enhancing whiteness and brightness.
Pigments and Coatings
Improves whiteness, stability, and UV resistance in specialty paints and plastics.

FAQs for Antimony Trioxide
1. Is Antimony Trioxide toxic?
It should be handled with proper protection. Industrial exposure limits apply, but it’s safe under controlled conditions.
2. Can Sb₂O₃ be used in non-halogen flame retardants?
It is primarily effective with halogen systems. For non-halogen solutions, alternatives may be preferred.
3. What’s the difference between fiber-grade and general-grade Sb₂O₃?
Fiber-grade offers finer particle sizes and lower impurities for PET spinning systems.
4. Do you provide COA and SDS?
Yes. We provide a Certificate of Analysis, SDS, and technical datasheet with every shipment.
5. Is the product REACH and RoHS compliant?
Yes. Our Sb₂O₃ complies with major global regulations including REACH and RoHS.
