Melapur MP is colorless to white monoclinic crystals or prisms or white powder. 
Melapur MP sublimes when gently heated.
Melapur MP having hydrogen bonded thereto from about 0.5 to about 1.5 moles of phosphoric acid per mole of melamine phosphate, particleboard containing said melamine phosphate material and processes for the production thereof, are disclosed.
Melapur MP is a triamine compound first discovered and synthesized in the early 1800s. 

Melapur MP is deaminated to the oxytriazine structural analogs ammeline, ammelide, and cyanuric acid. 
Melapur MP is a compound used for syntheses of a large variety of materials for applications such as cleaning supplies, dry erase boards, and plastics. 
Melapur MP is synthesized from urea, requires several purifications steps, and is marketed in various purities where the lowest quality is contaminated with oxytriazines.

Melapur MP is a kind of intumescent flame retardant with excellent properties. 
Melapur MP are salts with organic or inorganic acids such as boric acid, cyanuric acid, and phosphoric or polyphosphoric acid.
Melapur MP is a salt of melamine and phosphoric acid. 
Above 200 ºC, Melapur MP reacts to release water, resulting in a heat sink and leaving the phosphorous component available to react synergistically with other flame retardant components. 

Therefore, Melapur MP flame retardant is often used in blended flame retardant systems for applications, such as coatings and sealants.
Melapur MP (melamine phosphate) is a salt of melamine and phosphoric acid
Melapur MP is a melamine phosphate-based, halogen-free, flame retardant. 
Melapur MP offers significant advantages in terms of fire safety such as lower smoke density & toxicity and less corrosive gases. 

Like APPs, Melapur MP are also substances combining the synergistic effect of nitrogen- with phosphorus-containing components in one salt. 
Based on increasing thermal stability the Melapur MP can be ranked as follows: Melapur MP < melamine pyrophosphate < melamine polyphosphate . 
Above ∼200 °C Melapur MP will react with melamine pyrophosphate with release of reaction water, which will result in a heat sink. 

Above ∼260 °C melamine pyrophosphate will react with release of reaction water with melamine polyphosphates which again results in a heat sink effect.
Above 350 °C, melamine polyphosphate undergoes endothermic decomposition thus acting as a heat sink and cooling the combustion source. 
Compared to APP,  Melapur MP is more thermally stable and less sensitive to hydrolysis, but Melapur MP's FR effect is lower than that of APP, so it could not replace APP in intumescent coatings and polyolefin FRs. 

Melapur MP was originally developed for glass fiber-reinforced (GF) PA 66 and gives a V-0 at 25% dosage, but it fails to improve the flammability characteristics of PA 6 at reasonable levels
Melapur MP depolymerizes at above 350 °C, inducing significant cross-linking (as evidenced by increase in viscosity) in PA 66 and leading to a drastic depolymerization of PA 6.
Melapur MP is today mostly used in combination with other FRs, such as metal phosphinates (see phosphinate chapter), metal hydroxides, and phosphates. 

Melapur MP is characterized by its good thermal stability and a low impact on the glass-transition temperature (Tg). 
Melapur MP decompose endothermically (heat sink) and release inert nitrogen gases (e.g. ammonia) that dilute oxygen and the flammable gases in the flame. 
Often phosphoric acid is also formed as a decomposition product and promotes the formation of insulating char on the surface of the polymer.

Melapur MP decomposes endothermically above 350ºC, acting as a heat sink to cool the polymer. 
The released phosphoric acid further reacts with the polymer to form a char and inhibit the release of free radical gasses into the oxygen phase. 
Simultaneously, nitrogen species released from the degradation of melamine intumesces the char to further protect the polymer. 
Melapur MP based halogen free flame retardants are primarily used for glass fiber reinforced polyamide and polyester (e.g. PBT) and can be used as a synergist in many other applications and polymers.

Melapur MP is a coordination compound that has been used as an antimicrobial agent and polymer retardant. 
Melapur MP also has an electrochemical impedance spectroscopy (EIS) that can be used for determining the rate constant of its reaction with water vapor. 
The rate constants are determined by measuring the change in impedance over time and plotting it against frequency. 
This analytical method is used for determining the concentration and stability of melamine polyphosphate in solution and can be applied to other similar compounds.
