SGS Ammonium Polyphosphate Flame Retardant
Non-Toxic White Powder Ammonium Polyphosphate Flame Retardant For Intumescent Fireproof Paint
Ammonium polyphosphate (phase川is a non-halogen fiame retardant, it acts a fiame retardant by intumescence mechanism. When APP I1 is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia, The polyphosphoric acid reacts reacts with hydroxy groups to form a nonstable phosphateester. Following dehydration of the phosphate ester, a carbon foam is built up on the surface and acts as an insulation layer.
TF-MF201 is based on TF-201, ammonium polyphosphate phase II, coated by melamine-formaldehyde resin, With the MF coat, the advantage of TF-MF201 is extremely low water solubility, even in high-temperature water. Benefits this advantage, it's widely used in steel paint, especially in the weather-resistant situation.

Basic concept of intumescent
●Intumescent is a substance which swells as
a result of heat exposure, thus increasing in
volume, and decreasing in density.
●Expansion is pormally around 40-60 times
the applied DFT
●Char of low. thermal conductivity that
reduces heat transter t10 substrate
● Thermal insulation of substrate
