APP -203 by Oceanchem Group is an ammonium polyphosphate. Acts as a flame retardant. It is non-hygroscopic and non-flammable. The crystal modification is phase II. It is manufactured from APP-201 by micro-encapsulation with melamine resin. Offers lower viscosity in aqueous suspensions and lower heat stability in the temperature range greater than 300°C. It is slightly soluble in water even at elevated temperatures and completely insoluble in organic solvents. APP -203 is compatible with PP, PE, PA, PVC, PBT, PU and rubber.
