What is Ammonium Polyphosphate?
Ammonium Polyphosphate (APP) is a white, odorless, non-toxic inorganic compound primarily used in fire retardants and fertilizers. It is a polymeric compound of phosphoric acid with ammonia, having excellent thermal stability and low solubility. Depending on the degree of polymerization, APP is widely favored in the market for its fire safety and nutrient value.
Common Applications
- Flame Retardants: Used to enhance the fire resistance of intumescent plastics, coatings, and textile systems.
- Construction Materials: Fireproofing coatings on steel, foam, and wooden structures.
- Agriculture: As a slow-release fertilizer containing phosphorus and nitrogen.
- Paints & Coatings: Used as a fire resisting agent in industrial and decorative fire-resistant coatings.
- Adhesives & Sealants: Used in construction as flame retarded and thermally stable industrial grade formulation.
- Rubber & Foams: Used in flame retardant insulation and sealing products.
