Halogen Free Ammonium Polyphosphate APP,
REACH Ammonium Polyphosphate APP
Environmentally Friendly Halogen Free Flame Retardant of Phosphorus Nitrogen Base for Polypropylene
As additives in the paints, and coating. Ammonium Polyphosphate function as a dehydrating agent to take away hydrogen and oxygen atoms in organic to foam carbon layer matter. Ammonia is released in these reactions. In connection with phosphorus, the nitrogen appears to enhance the attachment of the phosphorus to the polymer. The viscous polyphosphoric acid liquid covers the surface of the substrate and isolates the air to achieve the purpose of flame retardancy.
