Plastic: a modern material

Plastic is an inexpensive and versatile material which is used to make many objects. For example, it is good for making containers because is resistant to chemical changes. It is also a good insulator since it does not conduct electricity.
There are different types of plastics, such as:

• Polystyrene, for making plastic bags.
• Expanded polystyrene, for packing and containers.
• Bakelite, an insulating material for making pot handles.
• Rubber, for making car or bikes tyres.
• Polyester, for making clothes.

However, not everything about plastic is good. Plastic is not biodegradable. This means it remains in nature for several hundred years, polluting the environment. To reduce this pollution, people have started to recycle plastics instead of just throwing them in the rubbish bin.
