GEOLOGY

Detailed explanation-1: -The short answer to the question “is plastic a good insulator” is yes, it is. Plastic conducts neither heat nor electricity, making it well-suited to electrical applications.

Detailed explanation-2: -Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Detailed explanation-3: -Why is plastic a good insulator? Plastics are poor heat conductors, because they have virtually no free electrons available for conduction mechanisms like metals.

Detailed explanation-4: -Plastics are generally good conductors of electricity.

Detailed explanation-5: -Materials such as plastic are bad conductors of electricity. They do not allow electricity to flow through them. A plastic covering is wrapped around electrical wires, to protect us from electric shocks.
