The flow of electricity is called current. Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Is rubber a good insulator?

In either its natural or synthetic form, rubber has been used as an insulator since 1870. Keeping electricity bound within the material is the main goal of an insulator – making rubber a very good choice, especially in the form of electrical mats.

Is rubber a good example of a conductor?

Rubber, plastic and glass are all good examples of insulators or insulating materials. These materials do not conduct electricity, as opposed to conductors or conducting materials (such as copper, aluminum, etc.). These are used to complete electrical circuits and allow flow of electricity.
