Insulator

An INSULATOR is any material that inhibits (stops) the flow of electrons (electricity).
An insulator is any material with 5 to 8 free electrons in the outer ring.Because, atoms with 5 to 8 electrons in the outer ring are held (bound) tightly to the atom, they CANNOT be easily moved to another atom nor make room for more electrons.
Insulator material includes glass, rubber, and plastic.
