An eraser is an insulator because it is made of materials, such as rubber or vinyl, that have high resistance to the flow of electricity. This property prevents the transfer of electric current, making the material an insulator.
A magic one is an insulator.
Conductor
An eraser is an insulator because it does not conduct electricity. It is typically made of materials such as rubber or vinyl which have high electrical resistance, preventing the flow of electricity through them.
Rubber is an insulator, meaning it does not conduct electricity. Therefore, electricity cannot pass through a rubber eraser.
In short, yes. The real question should be, isn't there a material that you can use that is superior to the conductivity of an eraser. <><><> Most chaklboard erasers are felt, which is NOT a conductor. When dry, a fairly good insulator.

It would be an insulator- chalk board erasers normally consist of two parts, a wooden handle and a soft pad that wipes off the chalk from the board. Neither of these parts are conductors of electricity.
Chalkboard erasers are made of felt. Felt is hair. Hair does not conduct electricity. Felt has lots of air entrained between the hair fibers so, it conducts heat poorly, too.

Note: "electricity" is not conducted, only electrical current (the flow of electrons) is. Electricity is the field that covers all things electrical. The wood in a pencil is an insulator. If it is wet, it is a poorer insulator, but only a poor conductor. The carbon (lead) in the pencil is a poor conductor. The metal holding the eraser is a good conductor. The rubber eraser is a poor conductor. You really have to address the conductivity of specific substances, not items that are build from a variety of substances.
