Ammonium polyphosphate
CAS No: 68333-79-9
Alias：APP
Molecular formula：H12N3O4P
Molecular weight：149.086741
Structural formula：
1.Performance and use
Ammonium polyphosphate is an inorganic polymer compound with a large number of phosphate and ammonium ions in its molecules, which can be regarded as a polymer composed of multiple ammonium phosphate molecules connected by phosphate groups. Ammonium polyphosphate is a white granular or powdery solid that is easily soluble in water and can slowly hydrolyze and release ammonia gas with the heating of water.
Ammonium polyphosphate can be used as a metal surface treatment agent to form a highly adhesive ammonium phosphate film, which can improve the adhesion and chemical stability of metal surfaces. It also has applications in the field of fire protection, and can be used to produce materials such as fireproof coatings, fireproof adhesives, and fireproof cellulose, which play a role in flame retardancy and fire prevention. It can also be used as an ingredient in oral care and anesthesia drugs, as well as in the manufacture of calcium ion detectors. It can be used as a dopant for semiconductor materials, a catalyst for the preparation of electronic components, and a renewable energy source. Ammonium polyphosphate is also a commonly used water treatment agent for purifying industrial wastewater, drinking water, and swimming pool water.

3. Packaging and storage
Packaging specification: 25kg/bag
Store in a dry and ventilated environment, and take moisture-proof measures such as sealed packaging and adding moisture-proof agents. Pay attention to controlling temperature, humidity, and oxygen concentration during storage, transportation, and use.
4. Safety protection
During the use of ammonium polyphosphate, attention should be paid to the use of masks, gloves, and protective goggles to avoid contact poisoning. Skin and eye contact should be avoided as much as possible. If accidentally touched, rinse immediately with water and seek medical attention as soon as possible. After use, tools and equipment should be cleaned in a timely manner to avoid long-term residual damage.
