Ammonium Polyphosphate (APP) Phase I
Featured inFlame Retardants
Ammonium polyphosphate Phase I (APP I) is a lower-polymerization-degree, water-soluble intumescent flame retardant suited for textile backcoating, paper treatment, and aqueous formulations. With a polymerization degree of approximately 10–100, it dissolves readily in water, enabling straightforward incorporation into waterborne systems. APP I releases phosphoric acid and ammonia upon heating, creating an efficient char-forming mechanism for cellulosic substrates.
