Ammonium polyphosphate-II APP-II
Ammonium polyphosphate-II (APP-II) from Henan Foremost Chem Co., Ltd. is a phosphorus-nitrogen intumescent flame retardant supplied as a fine white powder. This Phase II variant has a higher polymerization degree than APP-I, delivering superior thermal stability and char formation for industrial coatings, adhesives and polymer compounds. The product is exported in bulk bags or sealed drums to maintain purity and handling safety during transit.
As a non-halogenated flame retardant, APP-II decomposes endothermically at high temperatures to release ammonia and water, diluting flammable gases while forming a protective carbonaceous layer. Typical applications include fire-rated paints, epoxy intumescent coatings and polyolefin compounds where UL 94 V-0 or equivalent ratings are required. Its low solubility in water and compatibility with most polymers make it a standard choice for manufacturers targeting construction and textile sectors.
Industrial buyers source APP-II for fireproof building materials, cable compounds and specialty chemicals where smoke suppression is critical. The product is shipped from Zhengzhou, China, with packaging and logistics tailored to bulk orders. Verification of exact polymerization degree, particle size distribution and heavy metal content is recommended before large-scale procurement.

Sourcing Ammonium polyphosphate-II APP-II from Henan Foremost Chem Co., Ltd. - China Import Guide
Before ordering APP-II from Henan Foremost Chem Co., Ltd., verify the exact polymerization degree, particle size distribution, and heavy metal content, as these directly impact performance in your application. Request a recent certificate of analysis and confirm whether the product meets the specific fire safety standards required for your end use, such as UL 94 or EN classifications.
Confirm logistics details such as packaging type (bags, drums, or bulk), loading port in China, and Incoterms (FOB or CIF) to ensure alignment with your supply chain. Lead times can vary based on order volume and production scheduling, so clarify these upfront. Payment terms like L/C or T/T should be negotiated with the supplier, as these are not specified in the listing.
For quality assurance, arrange for pre-shipment inspection of the APP-II to check for moisture content, particle size, and purity. Request samples for laboratory testing in your own formulations to validate compatibility. Ensure the supplier provides a material safety data sheet (MSDS) and any required compliance documentation for customs clearance and end-user safety.
