Ammonium polyphosphate(phase-II)
(CF-APP201)
Molecular formula : (NH4PO3)n n>1000
CAS No.: 68333-79-9
EINECS No.: 269-789-9
Model No.: CF-APP201
Ammonium polyphosphate(Phase II) is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism. When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphate ester. Following dehydration of the phosphate ester, a carbon foam is built up on the surface and acts as an insulation layer.

On account of low water-solubility, APP-II is specially suitable to be used as acid source for intumescent coatings. Intumescent coatings on the steel structure can meet the requirements the DIN4102 fireproofing grade. For polyurethane foams, APP-II is a suitable halogen-free flame retardant. APP-II has an excellent flame retardant effect in the fibre base material such as paper and wood products. Adding 15-20% APP-II to Casting resins based on epoxy resins or unsaturated polyester resins can reach UL 94-V0 grade.
High nutrient content in a clear,crystal-free fluid that is stable
under a wide temperature range and has a long storage life
Requires no moisture for dissolving due to its liquid form
Ensures prolonged phosphorus nutrition
Provides great efficiency of a phosphate fertilizer
Blends fairly easily with other nutrients and crop protection products
Frequently used as a starter fertilizer due to the nutrient content and chemical properties
Ammonium polyphosphate is an inorganic salt of polyphosphoric acid and ammonia containing both chains and possibly branching. Its chemical formula is [NH4 PO3]n(OH)2 showing that each monomer consists of an orthophosphate radical of a phosphorus atom with three oxygens and one negative charge neutralized by an ammonium cation leaving two bonds free to polymerize. In the branched cases some monomers are missing the ammonium anion and instead link to three other monomers.
The properties of ammonium polyphosphate depend on the number of monomers in each molecule and to a degree on how often it branches. Shorter chains (n1000),[1] but short polymer chains (e.g. pyro-, tripoly-, and tetrapoly-) are more soluble and show increasing solubility with increasing chain length.
Ammonium polyphosphate can be prepared by reacting concentrated phosphoric acid with ammonia. However, iron and aluminum impurities, soluble in concentrated phosphoric acid, form gelatinous precipitates or "sludges" in ammonium polyphosphate at pH between 5 and 7.[3] Other metal impurities such as copper, chromium, magnesium, and zinc form granular precipitates.[4] However, depending on the degree of polymerization, ammonium polyphosphate can act as a chelating agent to keep certain metal ions dissolved in solution.
