Product Description

CAS No.: 68333-79-9 Ammonium Polyphosphate Flame Retardant For Fire Protective Coating​

 

 

Molecular formula : (NH4PO3)n n>1000
CAS No.: 68333-79-9
EINECS No.: 269-789-9

HS CODE: 2835.3990
Model No.: TF-201

 

Product descriotion:

Ammonium polyphosphate (phase II 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.

 

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
