Ammonium Polyphosphate

Ammonium polyphosphate is non-toxic and odorless, does not produce corrosive gases, has low moisture absorption, and high thermal stability. These characteristics make it an excellent chemical product. From the perspective of physical properties, it appears as white granules or crystals, easily soluble in water (under low degree of polymerization), and insoluble in organic solvents. In terms of chemical properties, it easily reacts with metal ions to form stable complexes, and can also form ammonium salts and phosphates. In terms of thermal stability, although it decomposes and produces ammonia and toxic gases during heating, as long as it is stored under sealed conditions, it can effectively avoid safety hazards. In addition, depending on the degree of polymerization, ammonium polyphosphate may vary in water solubility, decomposition temperature, and other aspects. Ammonium polyphosphate with high degree of polymerization has good water insolubility, high decomposition temperature, and wider application advantages.

Ammonium polyphosphate is a phosphorus-nitrogen type halogen-free flame retardant. It has high content of P and N flame retardant elements, ammonium polyphosphate has good thermal stability, almost neutral, non-toxic and low smoke. Ammonium polyphosphate can be used in engineering plastics, rubber conveyor belts, and intumescent fire retardant coatings.Ammonium polyphosphate has low water solubility, low processing viscosity, and high flame retardancy. When used in coatings, It has better rheology and stability. With the same addition amount, Taixing’s ammonium polyphosphate has a higher expansion rate and denser carbon layer, generate a longer fire protection time.

Ammonium polyphosphate (APP): an excellent choice for efficient and environmentally friendly flame retardants

Product details introduction:

1. Efficient flame retardant performance

Ammonium polyphosphate decomposes into polyphosphate and ammonia at high temperatures. Polyphosphate can promote the formation of a carbonized layer on the surface of materials, isolating oxygen and heat, while ammonia dilutes the concentration of combustible gases, thereby achieving excellent flame retardant effects.

2. Low smoke and low toxicity

During the combustion process, the APP can significantly reduce the release of smoke and toxic gases, reduce the harm of fires to the environment and human health, and is particularly suitable for places with high safety requirements.

3. Excellent thermal stability

The APP has a high thermal decomposition temperature (≥ 250 ℃) and can maintain stability in high-temperature environments, making it suitable for various high-temperature processing techniques.

4. Environmental protection and safety

Ammonium polyphosphate does not contain halogens and heavy metals, is non-toxic and harmless, complies with environmental regulations such as RoHS and REACH, and is a green and environmentally friendly flame retardant material.

5. Good dispersibility

The APP has good dispersibility and can be evenly distributed in the material, ensuring the stability and consistency of the flame retardant effect.
