what is Melamine polyphosphate

Flame Retardant Prowess: MMP is a halogen-free, nitrogen-phosphorus expanding flame retardant. Its chemical structure enables it to interfere with the combustion process effectively. During a fire, it releases non-combustible gases such as ammonia and water vapor, diluting the flammable gas concentration and reducing the heat release rate. This not only suppresses the spread of flames but also forms a protective char layer on the material surface, acting as a barrier against heat and oxygen. For instance, in tests on plastics containing MMP, the time to ignition and the rate of flame propagation were significantly reduced compared to non-flame-retarded counterparts.

Environmental and Health Profile: As an environmentally friendly option, MMP offers advantages over traditional halogenated flame retardants. It minimizes the release of toxic and corrosive gases during combustion, reducing potential harm to both the environment and human health. Its low smoke emission and density are particularly valuable in enclosed spaces, improving visibility and reducing the risk of smoke inhalation during a fire.

Physical and Processing Attributes: Presented as a white powder, MMP is easy to handle and incorporate into various manufacturing processes. It exhibits good thermal stability, with a decomposition temperature above 350 ℃, allowing it to withstand the processing temperatures of many plastics, which can reach up to 300 ℃. Its low water solubility and non-hygroscopic nature ensure its stability during storage and use, preventing issues such as clumping or degradation due to moisture absorption.
