Which one of the following is an example of melamine used for making floor tiles?

Correct answer: (d) Thermo-setting plastic

Explanation

Melamine (melamine-formaldehyde resin) is a thermo-setting plastic used for floor tiles.

Thermosetting plastics harden irreversibly on heating, giving them heat resistance, rigidity and scratch-proof durability.

Unlike thermoplastics, PVC or polythene, they cannot be remelted and reshaped once set.
