Flame Retardant Ammonium Polyphosphate
Flame Retardant Ammonium Polyphosphate (AP730) is a Phase II intumescent flame retardant with the chemical formula (NH4PO3)n and CAS number 68333-79-9. It is supplied as a fine white powder, designed for incorporation into thermoset resins, coatings, textiles, and plastic formulations. The product functions through acid-catalyzed char formation, creating a protective barrier that limits heat transfer and oxygen diffusion during combustion. Its performance aligns with international fire safety standards for construction and consumer goods.
This compound is manufactured with a polymer chain structure that ensures thermal stability and low water solubility. Typical industry grades contain 70% to 75% phosphorus content by weight and exhibit a bulk density of 0.8 to 1.0 g/cm³. Packaging is available in 25kg polyethylene-lined paper bags or jumbo bags, standard for bulk chemical shipments. The material is non-halogenated and complies with RoHS and REACH directives, making it suitable for environmentally sensitive applications.
Buyers in the construction, electrical insulation, and textile industries use this additive to meet UL94, EN 13501-1, and ASTM E84 fire ratings. It is commonly blended with intumescent systems and synergists such as pentaerythritol or melamine. Importers should confirm the exact phosphorus content, particle size distribution, and thermal decomposition profile with the supplier. Packaging and shipping are typically handled under FOB Qingdao or CIF terms, with lead times of 10 to 15 days after order confirmation.

Sourcing Flame Retardant Ammonium Polyphosphate from Shouguang Puer Chemical Co.,Ltd. - China Import Guide
Before ordering, verify the phosphorus and nitrogen content via a third-party lab report, and confirm the thermal decomposition profile using TGA data. Request particle size distribution (D10, D50, D90) if the product will be used in coatings or fine plastics. Ensure the supplier provides a batch-specific certificate of analysis. Do not accept generic claims without documented test results tied to your order number.
Confirm Incoterms with the supplier: FOB Qingdao is common, but CIF or DAP may be available. Lead time is typically 10 to 15 days after payment, but can extend during Chinese holidays. Packaging must be moisture-sealed with inner polyethylene lining. Payment terms are usually TT in advance or LC at sight. Request a copy of the bill of lading and export declaration before shipment.
Upon arrival, inspect for moisture damage, caking, or discoloration. Perform a simple solubility test: 1g in 100ml water should show minimal dissolution. Use a sieve analysis to confirm particle size. Retain a sample from each batch for future quality comparison. Request a material safety data sheet (MSDS) and ensure it matches the chemical identity and hazards listed in your import documentation.
