Buy & Import Flame retardant 99% antimony trioxide from Hebei Tianao Technology Co., Ltd - Wholesale Supply

Antimony trioxide (Sb2O3) with 99% purity is a critical inorganic flame retardant used to enhance fire resistance in polymers when combined with halogenated compounds. It appears as a fine white powder with a melting point of 660 °C and a CAS number of 1309-64-4, consistent with industrial-grade specifications. This material is not a standalone flame retardant but acts synergistically with bromine or chlorine systems to reduce ignition and flame spread in thermoplastics and textiles.

The product meets standard requirements for purity, particle size, and moisture content expected in flame-retardant intermediates. Typical impurities include trace metals such as iron and arsenic, kept below 50 ppm in certified grades. It is manufactured through controlled oxidation of antimony metal or sulfide ores, ensuring consistent crystallinity and dispersion properties in polymer matrices. No surface treatments or coatings are indicated in the source data.

It is primarily purchased by manufacturers of automotive interiors, electrical enclosures, construction insulation, and synthetic textiles requiring compliance with UL94, IEC 60695, or EN 45545 standards. Buyers typically order in bulk quantities of 25 kg or 500 kg packs, with packaging in polyethylene-lined fiber drums. Trade terms such as FOB or CIF are commonly used, but exact MOQ and lead time must be confirmed directly with the supplier.

Frequently Asked Questions About Flame retardant 99% antimony trioxide from Hebei Tianao Technology Co., Ltd
Industrial-grade antimony trioxide for flame retardancy typically has a D50 particle size between 1 and 5 microns. Finer particles improve dispersion in polymer melts and enhance flame-retardant efficiency. Buyers should request a laser diffraction report to confirm particle distribution for their specific resin system.

Sourcing Flame retardant 99% antimony trioxide from Hebei Tianao Technology Co., Ltd - China Import Guide

Before placing an order, verify the actual purity level through a Certificate of Analysis using ICP-OES or XRF methods. Confirm the particle size distribution and moisture content, as these affect dispersion in polymers. Do not rely on supplier claims without third-party test data. Ensure the product is free from arsenic and lead contamination, especially if used in electronics or automotive components.

Confirm the Incoterms offered - typically FOB or CIF - and whether the supplier handles export documentation. Lead time is not stated and may vary from 15 to 45 days depending on production scheduling. Packaging is usually in 25 kg or 500 kg drums with inner polyethylene lining; request samples of the packaging material to assess moisture barrier integrity. Payment terms are not disclosed and must be negotiated directly.

Conduct a pre-shipment inspection for color consistency, absence of lumps, and proper labeling. Request a batch-specific test report for heavy metals and moisture. Ensure the product is accompanied by a Material Safety Data Sheet (MSDS) compliant with GHS. For large shipments, consider hiring a third-party inspector to verify quantity, packaging integrity, and compliance with your internal quality specifications.
