Product Description

APP Ammonium Polyphosphate Flame Retardant For Passive Fire Protection Of Steel


Shifang Taifeng is a manufacture of Ammonium Polyphosphate(APP) with 21years experience. APP TF-201,  equal to Clariant Exolit AP422, is a halogen flame retardant for intumescent paint . It is widely used for fire coatings on wood and steel, and also for plywood, wood plastic composites.

Description :

Ammonium polyphosphate (Phase II) is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism.

When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphateester. Following dehydration of the phosphateester, a carbon foam is built up on the surface and acts as an insulation layer.


1. Halogen-free and environmentally friendly flame retardant
2. Low water solubility, extremely low aqueous solution viscosity, low acid value
3. Good thermal stability, migration resistance and precipitation resistance
4. The particle size is extremely small, especially suitable for occasions with high particle size requirements, such as high-end fireproof coatings, textiles
Coating, polyurethane rigid foam, sealant, etc.;
5. Biodegradable into phosphorus and nitrogen compounds


Active and passive fire protection

Fire protection of steel can be done with two methods:


Active fire protection

●Methods that require a certain amount of motion and

response in order to react to put out the fre

●E.g. sprinkler systems, fire extinguisher systems

Passive fire protection

●Methods that contain, minimize the impact, or slow the

spread of the fire

●Contrary to active fire protection, the passive type does

not need a response before reacting to the fire

●E.g. intumescent coatings, boards, fire walls, foams


Packing : TF-201 25kg/bag, 24mt/20’fcl without pallets, 20mt/20’fcl with pallets. Other packing as request.


Storage: in dry and cool place, keeping out of moisture and sunshine, min. shelf life one year.
