Insulating materials have very low conductivity. They offer extremely high resistance to the flow of current. Insulators are used in electric devices to isolate conductors. Thus they should have a high dielectric strength and a high resistivity. Their mechanical properties are also important for practical use.
Insulators are divided into gaseous, liquid, solid. They are also divided into groups according to their heat resistance.
