Flame Retardant Ammonium Polyphosphate APP200

Flame retardant ammonium polyphosphate APP200 is a phosphorus-nitrogen non- halogen flame retardant,with a chemical formula of (NH4) n+2PnO3n+1. The polymerization degree of n here reaches 200, making it a high polymerization degree product.Flame retardant ammonium polyphosphate APP200 has high content of P and N flame retardant elements. Flame retardant ammonium polyphosphate APP200 has good thermal stability, almost neutral, non-toxic and low smoke. Flame retardant ammonium polyphosphate APP200 has low water solubility, low processing viscosity with high flame retardancy.

Chemical properties: APP200 has stable chemical properties and is not prone to chemical reactions with other substances. It can maintain its structural and performance stability in various complex environments. In high temperature environments, thermal decomposition reactions occur, releasing ammonia and phosphoric acid. Ammonia can dilute the surrounding oxygen concentration, suppress combustion reactions, while phosphoric acid forms a dense carbonization layer on the surface of the material. This carbonization layer can effectively prevent heat and oxygen from transferring to the interior of the material, thereby achieving efficient flame retardancy.

Physical properties: The appearance is white fine powder, with uniform particles and easy dispersion. Moderate density is beneficial for uniform addition in various materials. Almost insoluble in water, it avoids the problem of performance degradation caused by dissolution in humid environments, and also reduces the impact on the mechanical properties of materials.
