An insulator (used for insulation) is a material which has a high resistance to the flow of current. Insulation is used to keep two components which are at different voltages from touching, causing a short; the piece of insulation used is also called an 'insulator'.
Most plastics are good insulators, as are air, glass and ceramics.
