Product Description

Ammonium Polyphosphate Intumescent Halogen Free Flame Retardant in Rigid Foam Application


APP is widely used in intumescent fire retardant coating, polyethylene, polypropylene, polyurethane, epoxy resin, rubber products, fiberboard, and dry powder fire extinguishing agent, etc. It is a safe and efficient phosphorus-based non-halogen smoke suppressant flame retardant Agent. APP has high flame retardancy, dimensional stability, hydrolysis resistance, and heat resistance in rigid polyurethane foam. The generation of toxic and corrosive gases to rigid polyurethane foams is even comparable to similar non-flame retardant materials.


Model No.: TF-PU501


Product description:: TF-PU501 is solid composite halogen-free phosphorus-nitrogen containing intumescent flame retardant, it acts both in the condensed phase and the gas phase.


Appearance Gray powder
P2O5 content (w/w) 47%
N content (w/w) 8%
pH value (10% aqueous suspension, at 25ºC) 6.5-7.5
Moisture (w/w) 0.5%




1. expands when heated, efficient in smoke suppression.

2. Excellent water resistance
3. Halogen-free and none heavy metal ions.

4.pH value is neutral, safe and stable during production and use, good compatibleness, not to react with other flame retardant and auxiliary.


Application: TF-PU501 is used solely in flameproof treatment for rigid polyurethane foam. UL-94 V-0 can be achieved when total loading of 9% is reached, and total loading of 15% to achieve classification for burning behavior of building materials and products GB / T 8624-2012 B2 level.


Packing : 25kg/bag, 22mt/20’fcl without pallets, 18mt/20’fcl with pallets. Other packing as request.


Storage: in dry and cool place, keeping out of moisture and sunshine, shelf life two years.
