Not sure about platsic but the plastic casing is an insulator.
A metal wire is a conductor. It is the plastic layer round the wire that is an insulator.
conductor
Light bulb is itsef composed of many parts like filament wire and external casing of glass. Among which current flowes through the tugasten filament wire which is a 'conductor' of high resistance.

insulator
it is a conducter
Butyl rubber is an insulator, popular in covering wire.
A steel spoon is an excellent conductor of heat.ANSWER: Conductor
Solder will conduct electricity, so is not an insulator.
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.
A wire is a conductor. It is usually coated with an insulator to isolate the current flowing in the conductor portion of the wire from other things around the wire, like your hand.
It doesn't, it is a conductor of heat and electricity.
