Revise: Polymer PropertiesAn electrical insulator strongly resists the flow of electric current. Most polymers have this property, making them useful for covering electrical conductors.
A material that strongly resists the passage of electrical current.
Link the named property to the product’s function: PVC is an electrical insulator, so its covering helps prevent contact with live conductors.
