How Melamine Is Made?

Melamine can be manufactured from dicyandiamide, hydrogen cyanide, or urea. ... 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.

How is melamine formaldehyde manufactured?

Melamine formaldehyde is made from the polymerization of formaldehyde (chemical formula CH2O) with melamine (chemical formula C3H6N6). Polymerization is the chemical process in which two or more identical small molecules--called monomers--are linked to form a chain of polymers.

Where is melamine produced?

Chemical structure of melamine. Melamine decomposes at its melting point of 345 °C. Melamine is manufactured by decomposition of urea. Because the manufacture of melamine requires urea, melamine production plants are often located near a urea production plant.
