What type of polymer is melamine?

Introduction. Melamine (1, 3, 5-triamino-2, 4, 6-triazine) formaldehyde (MF) is one of the hardest and stiffest thermosetting polymers, which provides good properties and performance.

What is called thermoplastic?

Thermoplastics are a class of polymers that can be softened and melted by the application of heat, and can be processed either in the heat-softened state (e.g. by thermoforming) or in the liquid state (e.g. by extrusion and injection molding).

What is melamine known as?
