Hint: Melamine is a thermosetting plastic and is coated on the uniforms of the firemen's that protects them from the flames of the fire. Melamine is also used to make floor tiles, all kinds of fire resistant fabrics and also kitchenware.

Complete answer:
Melamine is a chemical used in the manufacturing of plastic dishes, cups, and other tableware. It gives the dishes a harder, more durable feel than standard plastic. It's the abundance and variety of colors and patterns, durability, and affordability of these plastic dishes that make them an appealing option
Melamine is a poor conductor of heat and resists fire. Most of the synthetic fibres are poor conductors of heat and electricity. However, melamine is used as a coating on the uniforms of firemen as they are flame resistant. It is also used in airplanes, buses etc. to prevent the spread of fire.

Additional information:
The use of melamine as fertilizer for crops had been envisioned because of its high nitrogen content. However, melamine is much more expensive to produce than are other common nitrogen fertilizers, such as urea. The mineralization for melamine is slow, making this product both economically and scientifically impractical for use as a fertilizer.

Melamine is sometimes illegally added to food products in order to increase the apparent protein content. Ingestion of melamine may lead to reproductive damage, or bladder or kidney stones, and bladder cancer. It is also an irritant when inhaled or in contact with the skin or eyes.
