CAS No.: 68333-79-9
Formula: (Nh4po3)N
EINECS: 269-789-9
Appearance: White powder
Purity: ≥99%
Grade Standard: Industrial Grade
Ammonium polyphosphate appears as a white powder and is a polyphosphate containing N and P. According to the degree of polymerization, it can be divided into oligomerization, medium polymerization and high polymerization. When the degree of polymerization is below 20, it is called oligomerization, which is water soluble. When the degree of polymerization is above 50, it is called high polymerization, which can be used as flame retardant.
Basic Information
Scope of Application
Ammonium polyphosphate is a widely used chemical substance, and its uses are mainly focused on the following aspects:
1. Fertiliser additives: as a nitrogenous fertiliser, ammonium polyphosphate can be directly absorbed and utilised by the plant root system, increasing the nitrogen content of the plant and promoting plant growth and development. In addition, it can improve soil properties and enhance the microbial vitality of soil, which is beneficial to the growth of crops.
2. Alleviate heavy metal pollution: Ammonium polyphosphate can also alleviate medium heavy metal pollution, thus promoting the growth of vegetation and improving the ecosystem.
3. Industrial applications: In the industrial field, ammonium polyphosphate has a wide range of applications, such as the manufacture of powder metallurgy, ceramics, composite materials, coatings, plastics, rubber, pigments, dyes, polymers and so on.
4. Disinfectant and cleaning agent: Ammonium polyphosphate can also be used as a disinfectant and cleaning agent, for example, it can be used to disinfect pools or as a cleaning agent for dust and dirt.
