Ammonium Polyphosphate
























Ammonium Polyphosphate



Identification


Synonyms: APP; Polyphosphoric acids, ammonium salts

CAS No.: 68333-79-9

Molecular Formula: (NH4PO3)n

Structural Formula (Phase II ) :

Application


1) Ammonium polyphosphate phase I: intumescent flame-retardant component for coating, wood, paper, plywood, cable, fiber, plastic, rubber, resin, component of fire-extinguishing dry-powder for fire of forest, oil-well, and coal mine.

2) Ammonium polyphosphate pase II: Due to its low solubility in water, Phase II Ammonium polyphosphate is particularly suitable as an "acid donor" for intumescent flame-retardant paints or coating, which is applied in steel structures, wood/plastic applied in building material, adhesives and sealants, non-halogenated flexible and rigid polyurethane foams, as well as cellulose-contained paper and wood products

3) Very low polymerization degree ammonium polyphosphate (phase I) can be applied as releasing-control fertilizer

Risks and Safety Information


Ammonium polyphosphate (APP) is not regulated as hazardous substance by UN

May cause slight skin irritation but not irritating to the mucous membranes.

S-Phrase S24/25 Avoid contact with skin and eyes. React with alkaline solutions to form ammonia and can contribute to eutrophication of stagnant waters.

For more information, please see MSDS
