Antimony(III) Oxide
Antimony(III) oxide from Foshan Richemical Industry Co., Ltd. is a chemical compound with CAS number 1309-64-4, supplied at 99% purity as antimony trioxide (Sb2O3). The product achieves a whiteness level of 95%, a critical attribute for applications where optical brightness matters. Its fine particle size distribution is tailored for homogeneous dispersion in polymers and coatings, ensuring consistent performance in downstream processes.
As a flame retardant synergist, this Sb2O3 grade is standard for use in plastics, textiles and electronics due to its ability to suppress combustion and reduce smoke generation. Typical industry specifications for antimony trioxide include a minimum Sb2O3 content of 99.0%, a maximum arsenic content of 0.05%, and a lead content below 0.1%, though these values should be confirmed with the supplier’s certificate of analysis. The compound is also used as a catalyst in polyester production and as a fining agent in glass manufacturing to remove bubbles and improve clarity.
Industrial buyers source this material for flame-retardant masterbatches, PVC formulations and ceramic glazes, where its thermal stability and low volatility are essential. The product is shipped in 25 kg or 50 kg bags, with packaging designed to prevent moisture absorption and contamination. Buyers should verify the particle size distribution, heavy metal content and residual moisture, as these directly impact performance in high-temperature applications.

Sourcing Antimony(III) Oxide from Foshan Richemical Industry Co., Ltd. - China Import Guide
Before ordering, verify the Sb2O3 content, whiteness and heavy metal levels against your application’s requirements. Request a recent CoA and confirm that the product meets ASTM E1613 or equivalent standards for antimony trioxide. Check if the supplier can provide lot-specific data, as batch-to-batch variation can occur.
Confirm packaging, Incoterms (commonly FOB or CIF for chemical shipments from China) and lead times, which may range from 10 to 20 days depending on production schedules. Clarify payment terms, as chemical transactions often use L/C or T/T with a 30% deposit. Ensure the packaging meets IMDG or IATA regulations if shipping by sea or air.
Inspect the material upon arrival for particle size, color and moisture content. Use a sieve analysis to check for agglomeration and a moisture balance to confirm the residual moisture is below 0.5%. For critical applications, conduct a pilot run to validate performance in your formulation before full-scale production.
