Answer:
plastics don't conduct any electricity whatsoever, so plastic is actually used in a wide variety of applications where their insulating, or "protecting" properties are needed. PVC is the most common insulator for electric wiring, I know, because my dad's friend works in electrical and that's what he mainly uses in his line of work, but anyway. yeah, so, plastic materials such as PVC also helps with the prevention of electrical shock. obviously if you were to touch a bare electrical wire you would either be in for a long hospital stay or a coffin. lol um so yeah materials such as PVC are very good and are always used in electrical wiring to not only prevent electrical shock, but to also to provide an insulator and is good for use in high temperatures.
