How Does Ammonium Polyphosphate Work in a Fire Extinguisher?

Ammonium polyphosphate, also known as AP, is a chemical compound that is used in fire extinguishers. It is found in the form of white crystals and has a molecular weight of about 250.

Ammonium polyphosphate works by releasing ammonium ions and phosphoric acid when it comes into contact with water or moisture. The ammonium ions react with the water to create ammonia gas which acts as a coolant and suppresses the fire. The phosphoric acid reacts with water to release heat.

Ammonium polyphosphate is a chemical compound that is used in fire extinguishers. It is a white crystalline powder that can be made into a paste, gel, or liquid. When it comes in contact with fire, it will break down to release ammonium phosphate and phosphoric acid.HOPEFLAM APP 221

Ammonium polyphosphate has many uses in the manufacturing industry. It can be used as an adhesive, a desiccant, a binder for paint pigments and plastics, and as an ingredient in various cosmetics.HOPEFLAM APP 230MF

It is also found in the insulation of transformers and power cables because it absorbs moisture from the air which prevents damage to electrical equipment caused by corrosion.HOPEFLAM APP 230S
