Plastics are both poor conductors of heat and electricity. Due to this property plastics are used in many appliances as either heat insulators or electrical insulators.
Insulators are materials poor conductors of either heat, electricity or both that are used to separate conduction of heat or electricity between good conductors.

Uses of plastics as heat insulators - poor conductors of heat:
- Plastics are used to make handles of home utensils like frying pans. This helps in prevention of heat from being transmitted from the pan to the handle.
- Plastics are used to make casing of home appliances such as electric kettles and jugs that hold hot liquids.
- Plastics are used to make the casing of flasks. Their poor heat conductivity prevents the loss or gaining of heat to/from the environment, keeping the contents of the flask in an almost constant temperature.

Plastic use as poor electric insulators - poor electric conductors:
- Plastics are used to make insulators that wrap up electric wires that are used to conduct electricity.
- Plastics are used in making casings of electric appliances to hold parts together to prevent short-circuiting that would occur if a good conductor was to be used.
