Melamine is used in plastic tableware
Melamine is a type of plastic used in tableware such as plates, bowls, cups, utensils, and mugs. It is a lightweight, durable, and heat-resistant material that is hard to break, chip, or scratch. Melamine tableware comes in a wide range of colours, shapes, and styles, making it aesthetically versatile.
Melamine is a nitrogen-based compound that is organic-based. It is made from urea, which is chemically broken down into cyanic acid. When combined with formaldehyde, melamine undergoes a reaction that transforms it into melamine resin, a highly durable thermosetting plastic. Unlike some plastics that can melt with heat, thermosetting plastics permanently harden after their initial formation.
