Melamine is an organic base and a trimer of cyanamide, with a
1,3,5-triazine skeleton. Like cyanamide, it contains 67% nitrogenby mass and, if
mixed with resins, has fire retardant properties due to its release of nitrogen
gas when burned or charred, and has several other industrial uses. Melamine is
also a metabolite of cyromazine, a pesticide. It is formed in the body of
mammals that have ingested cyromazine.It has been reported that cyromazine can
also be converted to melamine in plants.
Melamine combines with cyanuric acid and related compounds to form melamine
cyanurate and related crystal structures, which have been implicated as
contaminants or biomarkers in Chinese protein adulterations.
Melamine is combined with formaldehyde to produce melamine resin, a very 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.
The use of melamine as fertilizer for crops had been envisaged during the 1950s
and 1960s because of its high nitrogen content (2/3). However, melamine is much
more expensive to produce than are other common nitrogen fertilizers, such as
urea. To be effective as a fertilizer, it is essential that the plant nutrients
are released or made available in a manner that matches the needs of the growing
crop. The nitrogen mineralization process for melamine is extremely slow, making
this product both economically and scientifically impractical for use as a
Melamine and its salts are used as fire-retardant additives in paints, plastics,
Melamine derivatives of arsenical drugs are potentially important in the
treatment of African trypanosomiasis.
Melamine use as non-protein nitrogen (NPN) for cattle was described in a 1958
patent. In 1978, however, a study concluded that melamine "may not be an
acceptable non-protein N source for ruminants" because its hydrolysis in cattle
is slower and less complete than other nitrogen sources such as cottonseed meal
Melamine is sometimes illegally added to food products in order to increase the
apparent protein content. Standard tests, such as the Kjeldahland Dumas tests,
estimate protein levels by measuring the nitrogen content, so they can be misled
by adding nitrogen-rich compounds such as melamine. An instrument (SPRINT)
developed by the company CEM Corp allows the determination of protein content
directly in some applications; the instrument cannot be fooled by adding
melamine in the sample.
Melamine is also used as a nitrogen and carbon source for N-doped carbon
nanotube. N-CNTs can be prepared via Chemical Vapor Deposition(CVD) method by
pyrolysizing melamine under an Ar atmosphere in a horizontal glass tube. A thin
film of iron (5 nm) is first deposited on a Si/SiO2 wafer. N-CNT synthesis
occurs at a furnace temperatures between 800 and 980 °C.
