Insulators Block the Free Flow of Electrons.

High Voltage Transmission Line Insulator - Howrah 2011-03-19 1874

Insulators have extremely few free electrons. They are all tightly bound to their parent atoms and they can't move. If the electrons can't move, current can't flow.

There are examples of plastics where conducting materials have been added. These include anti-static plastic bags and foam rubber blocks

Static Electricity - Electrons Repel Each Other - Like Charges Repel

Static Electricity - Opposite Charges Attract
