Melamine
Melamine is a nitrogen-containing heterocyclic amine that is used as a flame retardant, plasticizer, and textile dye. Melamine, also called cyanuramide or triaminotriazine, a colourless crystalline substance belonging to the family of heterocyclic organic compounds, which are used principally as a starting material for the manufacture of synthetic resins. Melamine is rich in nitrogen, a property that is similar to protein.

Description
Melamine forms synthetic resins with formaldehyde. It remains largely non-metabolized in male Wistar rats with 90% of the administered dose excreted in the urine and thus acts as a non-protein nitrogen food additive found in milk. Drinking water contaminant candidate list 3 (CCL 3) compound as per United States Environmental Protection Agency (EPA), environmental, and food contaminants. Melamine is an organic-based, nitrogen-rich compound used to manufacture cooking utensils, plates, plastic products, and more. Melamine resin is durable, fire and heat resistant and virtually unbreakable, making melamine products more desirable than other plastic housewares.

Melamine is a nitrogen-containing heterocyclic amine that is used as a flame retardant, plasticizer, and textile dye. The toxicity of melamine has been evaluated in animal studies, which showed that it has low acute oral toxicity but high inhalation and dermal toxicity profiles. The acute effects of melamine are due to its capacity to bind to the erythrocyte membrane and cause hemolysis. Melamine can also react with cyanuric acid to form cyanuramide, which can be detected by gas chromatography/mass spectrometry (GC/MS) analysis. The carcinogenic potential of melamine has not been determined, but there is evidence that it may be genotoxic and have the potential to induce cancer in humans.
Manufacture and applications of melamine
Melamine can be manufactured from dicyandiamide, hydrogen cyanide, or urea. Modern commercial production of melamine typically employs urea as a starting material. Urea is broken down to cyanuric acid, which then can be reacted to form melamine. Its most important reaction is that with formaldehyde, forming melamine-formaldehyde resins of high molecular weight. These compounds form under the influence of heat and then become fixed into an insoluble and infusible mold; this process is known as thermosetting. Melamine-based thermoset materials contain cross-linked polymers, which make the fixed molds strong and durable. Usually formulated with fillers and pigments, melamine resins can be molded into dishes, containers, utensils, handles, and the like or used as laminating agents or coating materials for wood, paper, and textiles. Formica and Melmac are well-known trade names for products based on melamine resins.
Melamine has also been incorporated into a variety of flame-retardant materials. This application is based on the compound’s high nitrogen content. When exposed to heat, melamine degrades and releases nitrogen. The freed nitrogen takes the place of oxygen in the surface air surrounding the material, which prevents the material from burning. Butylated melamine resins, made by incorporating butyl alcohol into the melamine–formaldehyde reaction mixture, are fluids used as ingredients of paints and varnishes. A copolymer containing melamine, formaldehyde, and sodium bisulfite produces a foam with sound-absorbing and flame-retardant properties. The foam has a notably hard microbubble structure, which gives it an abrasive quality that has been utilized in the development of cleaning products.

Chemical Properties
Applications
Melamine is used in the production of synthetic resins such as melamine resin with formaldehyde, which is used in high pressure decorative laminates like formica, melamine dinnerware, laminate flooring, and dry erase boards. The presence rich in nitrogen content resulted in fire retardant properties when mixed with resins. It is used to prepare melamine cyanurate by reacting with cyanuric acid. It finds application as superplasticizer for making high-resistance concrete, soundproofing material and in polymeric cleaning products like magic eraser. It is an active component in pigment yellow 150. Further, it is also used as a nitrogen and carbon source for N-doped carbon nanotube.

Melamine is the organic compound with the formula C3H6N6. This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton. It is widely used in production of certain plastics, e.g. Formica. Like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred.
DESCRIPTION
In one large scale application, melamine is combined with formaldehyde and other agents to produce melamine resins. Such resins are characteristically durable thermosetting plastic used in high pressure decorative laminates such as Formica, melamine dinnerware, laminate flooring, and dry erase boards.
Melamine foam is used as insulation, soundproofing material and in polymeric cleaning products, such as Magic Eraser.
Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.
Melamine also enters the fabrication of melamine poly-sulfonate used as superplasticizer for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during its handling and pouring. It results in concrete with a lower porosity and a higher mechanical strength, exhibiting an improved resistance to aggressive environments and a longer lifetime.
