Product Description

APP201 Non-Halogen Intumescent Flame Retardant Ammmonium Polyphosphate Flame Retardant


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.
