This looks like a course or test question, and is best answered by your course materials.
A potholder is an insulator. Its purpose is to insulate against the heat of the pots that you pick up.
Have a little think about what the purpose of a table mat is and you'll get your answer.
Asphalt is a poor conductor of electricity and can be considered a good insulator for that purpose. However, it is not a good insulator for thermal energy, as it conducts heat readily.
The purpose of a radiator is to transfer heat as quickly as possible. It is pretty much the opposite of an insulator.

Skirts on an insulator help to increase the leakage distance, providing better insulation performance. They help to prevent leakage currents and improve the overall efficiency and reliability of the insulator in high-voltage applications.

wool is a insulator
Conduction or insulation depends on material, not shape or purpose. A metal blade is a conductor.
Mica is an insulator of electricity and heat.
