Plastic can be divided by mechanical-thermal behavior in Thermoplastic, Thermosetting polymer and Elastomer. Thermoplastic consists of long linear molecules that are not interlinked. They are easily deformable and sensitive to heat. Thermosetting polymer consists of strong interlinked molecules and cannot be deformed. Elastomers consist of entangled molecules and can be pulled.
