A material which can be repeatedly reheated and reshaped, allowing it to be recycled after its initial use. Thermoplastics have long linear chain molecules held by van der Waals forces.
A material at room temperature that can be deformed under pressure and also return to original once pressure is released. Elastomers have weak bonds that can be stretched.
