Ammonium Polyphosphate APP-II, CAS No. 68333-79-9, is a white, free-flowing powder with the chemical formula (NH4PO3)n, where n exceeds 1000. This grade from Shandong Shian Chemical Co., Ltd delivers phosphorus content of 31.0-32.0% (w/w) and nitrogen content of 14.0-15.0% (w/w), with a neutral pH range of 5.5-7.5 in a 10% suspension. It exhibits low moisture content at ≤0.25% (w/w) and begins thermal decomposition at 275°C, maintaining stability in industrial applications.
The material has a density of approximately 1.9 g/cm³ at 25°C and a bulk density of about 0.7 g/cm³, with viscosity in a 10% suspension at 25°C capped at 100 mPa.s. Its solubility in water is minimal at 0.5 g/100cm³, and the average particle size is around 15 micrometers. APP-II is standard for applications requiring low water solubility, such as intumescent coatings and flame-retardant additives, where controlled release of phosphorus is critical.
Industries use SHIAN-APP-II as an acid source for intumescent coatings on steel structures, meeting DIN4102 fireproofing standards, and as a halogen-free flame retardant in polyurethane foams. It is also effective in fibre-based materials like paper and wood, and adding 15-20% to epoxy or unsaturated polyester resins achieves UL 94-V0 flame retardancy. Buyers typically source this for fire protection, construction, and industrial composite applications, with trade terms and packaging tailored to bulk chemical logistics.

Before ordering APP-II from Shandong Shian Chemical Co., Ltd, verify the exact phosphorus and nitrogen content ranges to ensure they align with your formulation requirements. Request a recent Certificate of Analysis (CoA) to confirm compliance with the specified pH, moisture, and particle size values, as these directly impact performance in coatings and composites.
Confirm the available Incoterms, such as FOB or CIF, and the port of loading in China, as Shandong’s location may influence logistics costs. Discuss lead times, which can vary based on production schedules, and clarify packaging options to ensure compatibility with your handling systems. Bulk shipments typically use 25 kg bags or 1 MT big bags.
Conduct quality checks on arrival, including testing for pH, moisture content, and particle size distribution. For fireproofing applications, ensure the material meets DIN4102 or UL 94-V0 standards as required. Request Material Safety Data Sheets (MSDS) and any third-party test reports, such as REACH compliance documentation for the CAS number 68333-79-9.
