About Ammonium Polyphosphate
Ammonium Polyphosphate (APP) is a versatile inorganic salt of polyphosphoric acid and ammonia. It is categorized primarily by its degree of polymerization and water solubility, with long-chain, water-insoluble forms being the industry standard for high-performance flame retardancy in plastics and coatings.
In the Indian market, APP is a critical component for manufacturers of intumescent paints used in commercial infrastructure and for the automotive and electrical sectors requiring UL-94 V-0 flame retardancy ratings. Its popularity is driven by the shift toward halogen-free, environmentally sustainable fire safety solutions in domestic manufacturing.
When procuring APP in India, buyers should prioritize the degree of polymerization (n-value) and water solubility levels, as these dictate the compatibility with specific resin matrices. It is recommended to request a Certificate of Analysis (COA) verifying the P2O5 content and particle size distribution to ensure consistent performance in compounding processes.

Frequently Asked Questions
What is the price of Ammonium Polyphosphate in India?
Ammonium Polyphosphate prices in India vary by grade, order quantity and delivery location, and move with market conditions. To get the current price for your requirement, submit an enquiry on Chemical Dekho and receive verified quotes from suppliers and manufacturers within 24 hours.
What is the difference between Phase I and Phase II APP?
Phase I is short-chain and water-soluble, while Phase II is long-chain, water-insoluble, and has higher thermal stability.
Is this product suitable for outdoor coatings?
Yes, specifically the high-polymer, water-insoluble grades are preferred for outdoor applications due to their moisture resistance.
Does APP release toxic fumes during a fire?
No, it is a halogen-free flame retardant that produces significantly less smoke and toxic gas compared to halogenated alternatives.
Can it be used in food-grade plastics?
No, this is an industrial-grade chemical and should not be used in food-contact materials unless specifically certified.
How does APP work in fire protection?
It decomposes to release phosphoric acid, which promotes char formation, creating an insulating barrier that prevents oxygen and heat from reaching the substrate.
