Product Description

High Efficiency APP Intumescent Flame Retardant For Itumescent Coating


TF series flame retardants are mainly based on ammonium polyphosphate and halogen-free and environmental-friendly products. 


Flame retardant mechanism of Phosphorus series flame retardant

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.


Advantage: It has good stability in water .

The stability test of APP phase II in 30℃ water 15days.

Appearance Viscosity slightly increased
Solubility(25℃, g/100ml water) 0.46
Viscosity(cp, 10% aq, at 25℃) <200
