The clue is in the name. Plastic means 'shapeable'. When they are first made these substances are soft enough to be squeezed out like toothpaste, flow into moulds with intricate shapes, rolled into thin sheets and be stamped into shapes like trays. When they cool they set in the new shape. Some set permanently and these are thermosetting substances such as we use for worktops. Others regain their plasticity when they are reheated carefully and we call them thermoplastics. Polythene is a familiar thermoplastic.
