KEY CONCEPTS OF PLASTIC MATERIALS

1. Plastics consist of long chains of atoms which are mostly composed of carbon.

2. Plastics can be classified into natural and synthetic.

3. The process of manufacturing plastic is called polymerisation.

4. Plastic materials are resistant, insulating, ductile, malleable, impermeable and light.

5. There are three types of plastic recycling processes: chemical and mechanical recycling and energy recovery.
