Product Description

Ammonium polyphosphate is an inorganic salt of polyphosphoric acid and ammonia containing both chains and possibly branching. Its chemical formula is H(NH₄PO₃)_nOH 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 (n < 100) are more water sensitive and less thermally stable than longer chains (n > 1000), but short polymer chains (e.g. pyro-, tripoly-, and tetrapoly-) are more soluble and show increasing solubility with increasing chain length.

Ammonium polyphosphate is used as a food additive, emulsifier, (E number: E545) and as a fertilizer.

Ammonium polyphosphate (APP) is also used as a flame retardant in many applications such as paints and coatings, and in a variety of polymers: the most important ones are polyolefins, and particularly polypropylene, where APP is part of intumescent systems. Compounding with APP-based flame retardants in polypropylene is described in. Further applications are thermosets, where APP is used in unsaturated polyesters and gel coats (APP blends with synergists), epoxies and polyurethane castings (intumescent systems). APP is also applied to flame retard polyurethane foams.

Production Usage

Inorganic additive flame retardant, used in the manufacture of flame retardant coatings, flame retardant plastics and flame retardant rubber products, etc.
It is mainly used in intumescent fire retardant coatings and thermosetting resins (such as polyurethane rigid foam, UP resin, epoxy resin, etc.), and can also be used for flame retardant of fiber, wood and rubber products. Since the APP has a high molecular weight (n>1000) and high stability, it can also be used as a main active ingredient of intumescent flame retardant thermoplastics, especially in PP up to UL 94-Vo for the manufacture of electronic parts.
