Thermoplastics are polymers that are easily melted and changed to another shape as many times as possible. They become molten when they are heated and solidify when cooled. Examples of thermoplastics include; polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamides, polyesters, and polyurethanes.
