insulator :)
Foam is not a good conductor; in fact, it is an insulator. Foam is made up of many small pockets of gas trapped within a solid or liquid material, which greatly hinders the flow of electric charge, making it a poor conductor of electricity.
A foam coffee cup is a good insulator because it contains air pockets within the foam that slow down the transfer of heat. The air pockets prevent heat from easily escaping or entering the cup, helping to keep the contents hot or cold for longer periods of time. Additionally, foam is a poor conductor of heat, further enhancing its insulating properties.

Its a insulator
A bulletin board is typically an insulator, as it is usually made of materials such as cork or foam that do not conduct electricity well. This means that it does not easily allow electric currents to pass through it.

Styrofoam, along with most other expanded plastics, is a very poor insulator of heat and electricity, thereby making a foam coffee cup a very good insulator.

This depends on the type of foam. There have been made foam that actually conduct electricity. This is a choice made in the manufacturing of the foam. Most foam in mattresses and the like does not conduct electricity. Moisture however can change the mattresses conductivity drastically.

is a pen a insulator of conductor
In a foam there is a large gap between the conduction band and the valence of band in the atoms makng up the foam. If any object is to conduct electricity through it the gap between the conduction band amd the valance should be minimun or overlapping so that the electrons in the valance band can go into conduction band and conduct electricity
