Import Ammonium Polyphosphate — Buy in Bulk from Supplier in China

Ammonium polyphosphate from Shifang Changfeng Chemical Co., Ltd is a Phase-II grade with the molecular formula (NH4PO3)n, where n exceeds 1000, and a CAS number of 68333-79-9. This long-chain polymer structure provides enhanced thermal stability, making it particularly effective as a flame retardant in plastics, coatings, and construction materials. Its high water solubility also supports agricultural use as a slow-release fertilizer.

The product is supplied as a fine white powder with a typical bulk density of 0.7 to 1.1 g/cm³, slightly lower than some shorter-chain variants. It meets standard industry specifications for phosphorus content, often ranging from 30% to 32% w/w, with nitrogen content typically between 13% and 15% w/w. The compound’s non-toxic and non-corrosive nature allows for safe handling under recommended conditions.

Industries such as agriculture, fire safety, and manufacturing rely on this compound for its dual functionality. In agriculture, it improves soil fertility and crop yield, while in fire safety, it reduces flammability in treated materials. Trade terms include FOB and CIF, with packaging usually in 25 kg or 1000 kg big bags. Confirm MOQ, lead time, and specific nutrient content directly with Shifang Changfeng Chemical Co., Ltd.
