Polythene is a soft plastic whereas bakelite is one of the hard plastics.
- Bakelite is a thermosetting plastic that is a poor conductor of heat and electricity. Hence, it is used to make electrical switches and handles of utensils.
- Polythene is a plastic obtained by the polymerisation of a chemical compound known as ethene. It is used in making polythene bags, waterproof plastic sheets, bottles, buckets, dustbins, etc.
- Thus, polythene is used in making packaging materials and bakelite being tough, is used for making electrical switches.
