Melamine Cyanurate Chemical Properties

Melamine Cyanurate Stability: it is generally stable under standard conditions but may degrade at high temperatures, especially above 300°C. Its stability can depend on the specific formulation and environmental conditions.

Reactivity: It exhibits flame-retardant properties, particularly in the presence of heat, as it can form a protective char layer on the material surface.

MCA Flame retardancy: It has excellent flame retardancy, the flame retardancy reaches UL94 V-0 level, and the smoke generation is small.

MCA Smoke suppression: It releases nitrogen, carbon dioxide and water during combustion, which helps to reduce smoke generation.

Combustion Performance: When exposed to heat or flame, melamine cyanurate forms a protective insulating layer of carbon, which helps in reducing the rate of combustion. This makes it a valuable additive for improving fire resistance in polymers.

Melamine cyanurate Toxicity: While melamine cyanurate is generally considered non-toxic in small quantities, it can be harmful if ingested in large amounts or improperly handled. Proper precautions should be taken during handling.

Melamine Cyanurate Application Features

Compatibility: Good compatibility with polymers, such as nylon resin, with minimal impact on mechanical properties.

Processability: It is not easily prone to sticking to the mold, foaming, or frosting during processing.

Dispersion: It is evenly dispersed in the polymer, with a reasonable particle size distribution and no agglomeration.

Lubricity: It provides a certain lubricating effect, helping to improve processing.

Conclusion

Melamine cyanurate is a flame retardant with excellent chemical properties and broad application potential. Its high nitrogen content, high melting point, superior thermal stability, and good compatibility and processability enable it to play a key role in the flame retardant treatment of plastics, rubber, nylon, polyurethane, and other materials.
