Intumescent Flame Retardant Additive 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.
