Melamine/Urea Urea is the basic material for the manufacture of plastics. It is a colorless crystalline substance that melts at 132.7°C and is used to produce melamine, which in turn is used to produce melamine resin. When melamine resin is combined with formaldehyde it produces a very durable thermoset plastic.
