Melapur MP 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.
