Ammonium polyphosphate (APP), is a chemical compound used as a flame retardant. It is composed of ammonium ions (NH4+) and polyphosphoric acid chains formed by the condensation of phosphoric acid (H3PO4) molecules. APP is widely used in various industries, especially in the production of fire-resistant materials. When exposed to heat or flames, APP decomposes and releases phosphoric acid, which reacts with the materials to form a protective layer. This layer acts as a physical barrier, preventing the fire from spreading further. The released phosphoric acid also dilutes the flammable gases around the fire, interrupting the combustion process.
APP is commonly added to plastics, textiles, coatings, and other materials to enhance their fire resistance. It can be incorporated into these materials during their production or applied as a coating afterward.
The use of APP in these applications helps to reduce the flammability of the materials and enhance their fire safety properties.
In addition to its flame retardant properties, APP also has advantages such as high thermal stability and compatibility with various materials. It does not release toxic gases or produce a significant amount of smoke during combustion, making it a favorable choice for fire safety.
Overall, Ammonium polyphosphate (APP) is an important flame retardant used in numerous industries to improve the fire resistance of materials. Its ability to form a protective layer and inhibit the spread of flames plays a crucial role in enhancing fire safety and reducing the risk of fire-related accidents.
Shifang Taifeng New Flame Retardant Co.,Ltd is a professional ammonium polyphosphate (APP) factory in China with 22 years of experience. TF-201 is Phase II, uncoated APP, which is used for fire proof coating, textile coating, wood coating and plastics.
