Ammonium Polyphosphate Flame Retardant APP-II from Shandong Shian Chemical Co., Ltd is a halogen-free, intumescent flame retardant with the chemical formula (NH4PO3)n, where n exceeds 1000. It appears as a white, free-flowing powder with a phosphorus content of 31.0 - 32.0% by weight and nitrogen content of 14.0 - 15.0% by weight. The product has a pH range of 5.5 - 7.5 in a 10% suspension, moisture content below 0.25%, and thermal decomposition temperature of at least 275°C, making it suitable for high-temperature applications.
The material has a density of about 1.9 g/cm³ at 25°C and a bulk density of about 0.7 g/cm³, with an average particle size of 15 micrometers. Its low water solubility (0.5 g/100 cm³) and viscosity below 100 mPa.s in a 10% suspension at 25°C allow for stable integration into coatings and polymers. Typical for APP-II grade flame retardants, it is used where minimal water solubility and high thermal stability are critical for performance.
This grade is particularly effective in intumescent coatings for steel structures, meeting DIN4102 fireproofing standards, and as a flame retardant in polyurethane foams, paper, wood products, and casting resins. For epoxy or unsaturated polyester resins, adding 15 - 20% APP-II can achieve UL 94-V0 flame retardancy. Buyers typically source this for industrial applications requiring halogen-free solutions, with bulk packaging and logistics tailored to chemical handling standards.

Before ordering, verify the exact phosphorus and nitrogen content ranges, as these directly impact the flame retardant performance in your specific application. Confirm the thermal decomposition temperature meets your processing requirements, especially if the material will be exposed to high temperatures during manufacturing or end-use.
Discuss logistics for chemical handling, including packaging type (e.g., 25 kg bags, bulk containers) and Incoterms such as FOB or CIF. Lead times for chemical shipments from China can vary, so clarify production schedules and port of loading, typically Qingdao or Tianjin for Shandong-based suppliers.
Request a certificate of analysis for each batch to confirm compliance with the specified pH, moisture, and particle size values. For intumescent coatings, ensure the APP-II meets DIN4102 or UL 94-V0 standards by conducting third-party testing. Inspect the material upon arrival for consistency in appearance, particle size distribution, and bulk density.
