Product Introduction
Ammonium Polyphosphate (APP) is an inorganic compound widely used as a flame retardant and fertilizer. It is available in various forms, including white powder, crystalline, or liquid, depending on the grade. APP is valued for its high phosphorus and nitrogen content, thermal stability, and low solubility in water.

Product Features
High Purity: Contains ≥31% phosphorus (P) and ≥14% nitrogen (N).
Thermal Stability: Decomposition temperature ≥270°C (Phase II).
Low Solubility: ≤0.5 g/100 mL in water, suitable for water-resistant applications.
Fine Particle Size: Average particle size ~15 μm, with 99% passing 45 μm.
Environmentally Friendly: Non-toxic, non-hazardous (under normal handling).
Applications
Flame Retardant: Used in plastics, coatings, textiles, and construction materials.
Fertilizer: Slow-release nitrogen and phosphorus source for agriculture.
Adhesives & Resins: Enhances fire resistance in wood composites and sealants.
