Ammonium Polyphosphate
Ammonium Polyphosphate (APP) Phase II from Oceanchem Group Limited is a white powder flame retardant with intumescent properties, supplied in bulk for industrial and agricultural use. The compound is a high-phosphorus, low-water-solubility polymer, formulated as (NH4PO3)n, and is offered in technical and fertilizer-grade purities to suit different processing needs. Its dual functionality as a flame retardant and slow-release NP fertilizer makes it a versatile input for polymer, textile, coating, and wood-product applications, as well as for agricultural nutrient programs.
The material is standard for applications requiring high phosphorus content with controlled release, typical in fire-resistant coatings and plastics where thermal stability and low smoke emission are critical. In agriculture, APP Phase II is valued for its ability to supply both nitrogen and phosphorus in a form that minimizes leaching, supporting efficient nutrient uptake in crops. The product’s polymerization degree and particle size distribution are engineered to meet performance targets in end-use formulations, with typical industry grades ranging from fine powders for coatings to granular forms for fertilizers.
Industrial buyers source this compound for manufacturing fire-safe materials, while agricultural distributors use it as a base for specialized fertilizers. Oceanchem Group Limited provides bulk quantities from Shandong, with the product packaged for export under standard handling conditions. Buyers should confirm packaging specifications, as bulk bags and intermediate bulk containers are typical for this category. The supplier’s location in Weifang offers logistical advantages for shipments from northern Chinese ports, with common Incoterms including FOB Qingdao or CIF to major hubs.

Sourcing Ammonium Polyphosphate from Oceanchem Group Limited - China Import Guide
Before ordering, verify the exact phosphorus and nitrogen content, polymerization degree, and particle size distribution with Oceanchem Group Limited, as these parameters directly impact performance in flame retardant and fertilizer applications. Request a recent certificate of analysis (COA) and, if applicable, third-party test reports for heavy metals and other contaminants to ensure compliance with your industry standards.
Confirm the packaging type and size, as APP is typically shipped in 25 kg bags or bulk bags of 500-1000 kg, depending on the buyer’s requirements. Discuss Incoterms such as FOB Qingdao or CIF to your nearest port, and clarify payment terms, which often include L/C or T/T. Lead times can vary, so request an estimated delivery schedule based on your order volume and destination.
For quality assurance, insist on pre-shipment inspection for particle size, moisture content, and pH value, as these can affect processing and end-use performance. Ask for samples to conduct in-house testing, particularly for flame retardant applications where thermal stability is critical. Ensure the supplier provides material safety data sheets (MSDS) and handling guidelines to comply with your local regulations.
