Melamine cyanurate is used in rubber, nylon, urethane, phenolic resin, polyethylene (PE), acrylic acid, lubricants and adhesives.
Melamine cyanurate is a crystalline complex consisting of a 1:1 mixture of melamine and cyanuric acid.
This substance is not a salt, despite its unsystematic name melamine cyanurate.
The complex is held together by an extensive two-dimensional network of hydrogen bonds between the two compounds, reminiscent of the guanine–cytosine base pairs found in DNA.
Melamine cyanurate forms wire-like crystals obtained from aqueous solutions.
Melamine derivatives and MCA show promising development for phosphorus-based FR polymers, especially P-N-containing FR compounds.
Melamine cyanurate provides only 40% of the heat of combustion of hydrocarbons.
Melamine cyanurate combustion produces nitrogen, which acts as an inert diluent.
Melamine cyanurate can also delay the loss of other flame retardant components (such as bromine and phosphorus).
Melamine cyanurate can capture these volatile compounds through salt formation.
Melamine cyanurate may continue to show flame retardant activity at a later stage.
Melamine cyanurate can also make a significant contribution to char formation during the swelling stage.
A strong nitrogen/phosphorus synergistic effect is attributed to the formation of nitrogen/phosphorus substances remaining in the coal, providing protection against further oxidation.
Melamine cyanurate can also act as a blowing agent in coal by increasing the barrier functionality of the coal layer.
The addition of melamine cyanurate and fillers causes processing and assembly difficulties.
Melamine cyanurate is a salt of melamine and cyanuric acid.
Melamine cyanurate has a higher thermal stability than pure melamine.
Melamine cyanurate remains stable up to approximately 320°C.
For this reason, Melamine cyanurate is generally applied to polymers with higher processing temperatures.
Melamine cyanurate undergoes endothermic decomposition above 320°C and turns into melamine and cyanuric acid.
Melamine cyanurate acts as a heat sink in this process.
The vaporized melamine acts as a source of inert gas, diluting the oxygen and fuel gases present at the point of combustion.
The released cyanuric acid reacts with the polymer to form a char that prevents the release of free radical gases into the oxygen phase.
Examples of suitable polymers are all nitrogen-based polymers such as polyamide 66, 6, 11, 12, thermoplastic polyurethane and polyurethane.
Melamine cyanurate provides easy application to EPS (expanded polystyrene) and non-woven fabrics when mixed with water-based adhesives.
