Question: what type on material is melmac melamine made of? 

Answer: "Melamine is a strong organic base with chemical formula C3H6N6, with the IUPAC name 1,3,5-triazine-2,4,6-triamine. It is primarily used to produce melamine resin, which when combined with formaldehyde produces a very durable thermoset plastic.
