AMMONIUM POLYPHOSPHATE

Ammonium salt of phosphoric acid. It is a high molecular weight fire retardant. To achieve a synergistic effect, ammonium polyphosphate is added to the formulation of fire retardant

 coatings together with pentaerythritol or melamine. ETS Group of Companies offers supplies of ammonium polyphosphate for the paint and varnish industry and the production of coatings

 for use in the production of such final products as:

intumescent fire-resistant coatings, for polyolefins (polypropylene, polyester and thermoplastic polyolefins)

polyurethane foams (hard, elastic and TPU)

thermosetting resins (epoxy, phenolic and unsaturated polyesters)

thermoplastic

textile coverings

paints

APPLICATIONS

Fire retardant coatings

AMMONIUM POLYPHOSPHATE 

Description:

Ammonium polyphosphate II crystalline phase. Ammonium Polyphosphate is an environmentally friendly flame retardant with nitrogen structure and halogen free.

Properties:

high degree of polymerization

good heat resistance

low hygroscopicity.

This product is a highly effective inorganic flame retardant.

Application:

for the production of fire retardant intumescent paints, varnishes and sealants for coatings of metal structures, cables and wood

in the production of products on a wooden basis (chipboard, fiberboard, plywood)

in the synthesis of a wide range of resins and plastics with reduced combustibility, flammability, smoke-forming ability, toxicity of combustion products and with reduced flame spread over the surface

in the production of fire-resistant compounds based on rubbers, rubbers, artificial leather, lubricants.

Ammonium polyphosphate commercially produced by Clariant, (former business area of Hoechst AG), Budenheim and other sources 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 (n<100) are more water sensitive and

 less thermally stable than longer chains (n>1000),[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. Other metal impurities such as copper, chromium, magnesium, and zinc form granular precipitates.

However, depending on the degree of polymerization, ammonium polyphosphate can act as a chelating agent to keep certain metal ions dissolved in solution.

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.[6] 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.

Ammonium polyphosphates as used as flame retardants in polymers have long chains and a specific crystallinity (Form II). They start to decompose at 240 °C to form ammonia and phosphoric 

acid. The phosphoric acid acts as an acid catalyst in the dehydration of carbon-based poly-alcohols, such as cellulose in wood. The phosphoric acid reacts with alcohol groups to form

 heat-unstable phosphate esters. The esters decompose to release carbon dioxide and regenerate the phosphoric acid catalyst. In the gas phase, the release of non-flammable carbon dioxide

 helps to dilute the oxygen of the air and flammable decomposition products of the material that is burning. In the condensed phase, the resultant carbonaceous char helps to shield the 

underlying polymer from attack by oxygen and radiant heat.Use as an intumescent is achieved when combined with starch-based materials such as pentaerythritol and melamine as expanding 

agents. The mechanisms of intumescence and the mode of action of APP are described in a series of publications.
