Purity 98%: Ammonium Polyphosphate with a purity of 98% is used in intumescent fire retardant coatings, where it enhances flame inhibition and smoke suppression. Molecular Weight 1000–5000: Ammonium Polyphosphate with molecular weight 1000–5000 is used in thermoplastic compounding, where it provides consistent char formation and reduces dripping. Particle Size D50 15 μm: Ammonium Polyphosphate with particle size D50 15 μm is used in epoxy resin systems, where it ensures homogeneous dispersion and increases mechanical strength retention after fire exposure. Melting Point 275°C: Ammonium Polyphosphate with a melting point of 275°C is used in engineering plastics, where it maintains fire performance in high-temperature processing environments. Thermal Stability 300°C: Ammonium Polyphosphate with thermal stability up to 300°C is used in fiberglass-reinforced composites, where it delivers long-term heat resistance and improved fire retardancy. Viscosity Grade Low: Ammonium Polyphosphate with low viscosity grade is used in acrylic emulsion paints, where it allows for easy application and stable fire protection properties. Water Solubility <0.01%: Ammonium Polyphosphate with water solubility below 0.01% is used in exterior wood treatments, where it offers durable fire retardancy and minimal leaching. Decomposition Temperature 280°C: Ammonium Polyphosphate with decomposition temperature of 280°C is used in paper impregnation, where it enables effective thermal insulation and enhances flame-retardant performance. |
| Packing | The packaging for Ammonium Polyphosphate is a 25 kg white woven bag, labeled with product name, grade, manufacturer, and safety information. |
| Container Loading (20′ FCL) | Container Loading (20′ FCL) for Ammonium Polyphosphate: Typically loaded with 20-25 metric tons, packed in 25kg or 1000kg bags, palletized or loose. |
| Shipping | Ammonium polyphosphate should be shipped in tightly sealed, moisture-proof containers to prevent clumping and hydrolysis. It should be transported as a non-hazardous chemical, kept away from strong acids and oxidizers. Recommended storage is in a cool, dry location. Handle with protective equipment to avoid inhalation or contact with skin and eyes. |
| Storage | Ammonium polyphosphate should be stored in a cool, dry, and well-ventilated area, away from moisture, heat, and incompatible materials like strong acids or alkalis. The chemical must be kept in tightly sealed containers to prevent clumping or decomposition. Storage areas should be equipped with proper labels and protective measures to avoid dust formation and accidental contact. Keep away from ignition sources. |
| Shelf Life | Ammonium polyphosphate typically has a shelf life of at least two years when stored in a cool, dry, and sealed container. |
