Melamine resin

Because of its high dielectric constant ranging from 7.2 to 8.4, melamine resin utensils and bowls are not microwave safe.

In the late 1960s the tendency of melamine cups and plates to become stained and scratched led to a decline in sales, and eventually the material became largely restricted to the camping and nursery markets, in which its light weight and resistance to breaking were valued.

The sheets are heavy for their size, and the resin is prone to chipping when being cut with conventional table saws.

[5] Melamine, with the addition of formaldehyde, cyanuric acid, and DETA (diethylenetriamine) has been demonstrated to bind CO2 for purposes of carbon capture, according to researchers at Stanford, Berkeley, and Texas A&M.

[9][10] Melamine-formaldehyde resin forms via the condensation of formaldehyde with melamine to give, under idealized conditions, the hexa-hydroxymethyl derivative.
