Description

Melapur 200 is a melamine polyphosphate based halogen free flame retardant. It 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. 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.
