Description of MPP (Melamine polyphosphate):
MPP (Melamine polyphosphate) 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.
MPP (Melamine polyphosphate) 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.

MPP (Melamine polyphosphate) is a melamine based halogen free flame retardant for glass fiber reinforced polyamide 66 and suitable to use in thermosetting, thermoplastic formula, especially PUR and also be widely used in PBT, PET, PA.
MPP (Melamine polyphosphate) is a nitrogen-phosphate composite flame-retardant, melamine polyphosphate was prepared through a simpler, less energy-consuming and environment-friendly synthesis method compared with the conventional one.
The obtained MPP (Melamine polyphosphate) was characterized by Fourier Transform Infrared spectra (FT-IR) and solid-state NMR, and the conversion ratio was determined through the weight-loss caused by the ammonia release during the condensation.
Glass fiber-reinforced polyamide 66 was flame retarded by this synthesized MPP, and the combustion and charring behavior were investigated.
Additionally, the practical flame retardance including UL94 vertical burning test and Limiting Oxygen Index measurement were conducted for the comparison with the existing commercial MPP system.

MPP (Melamine polyphosphate) was applied as reactive and additive flame retardant for thermally resistant polyurethane foams.
MPP (Melamine polyphosphate) was hydroxyalkylated with ethylene and propylene carbonates to get oligoetherols with 1,3,5-triazine ring and phosphorus.
The structure and physical properties of the products were studied.
The polyurethane foams, PUFs obtained from this oligoetherols were self-distinguishing.
The addition of powdered MPP (Melamine polyphosphate) into foaming mixture resulted in further decrease of flammability modified PUFs.
The MPP (Melamine polyphosphate)-modified PUFs were characterized by physical methods adequate to thermal resistance and flammability of the PUFs.
The best MPP (Melamine polyphosphate)-modified PUF showed oxygen index 24.6.
All the modified PUFs were remarkably thermally resistant; they could stand long lasting thermal exposure even at 200 °C.
