Ammonium polyphosphate

Ammonium polyphosphate from Orichem International Ltd. provides a concentrated nutrient source with 31% phosphorus and 14% nitrogen by weight, formulated for industrial and agricultural use. The compound maintains a balanced pH between 5.5 and 7.0 in a 10% suspension, ensuring compatibility with diverse soil conditions. Its high water solubility accelerates nutrient uptake, making it suitable for large-scale fertilizer production and fire-retardant applications.

This grade is a crystalline solid, typically supplied as a fine white powder with a bulk density of 0.8 to 1.2 g/cm³. It meets standard agricultural specifications for phosphorus solubility, with a typical particle size distribution of 90% passing through a 150-mesh sieve. The product’s non-hygroscopic nature allows for stable storage under standard conditions, though it should be kept dry to prevent caking.

Primary buyers include fertilizer manufacturers seeking a slow-release phosphorus source and fire-retardant producers targeting construction and textile industries. The compound is also used in forestry for wildfire mitigation. Trade terms such as CIF and T/T are supported, with packaging typically in 25 kg or 50 kg woven bags.
