Thermoplastic insulation was used a few years ago and has now been upgraded to cross linked poly vinyl. The trade name used is X-link insulation. Rubber (Thermoset) is used in some outdoor extension cords.
One of the most commonly used one is rubber or a rubber-like compound.

Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
Polystyrene is a better insulator. It is often used as insulation on houses.
There are several physical effects that can produce electricity; it really depends in what form the energy is available. But one method that is used quite often to produce electricity in industry is converting movement energy to electricity with a generator.
Static electricity caused by friction.

Styrofoam can insulate heat well, hence it is often used to store food.
Interesting question. I suppose that Sodium Chloride is a solid substance in it's normal state, as mined in many parts of the world.(common table salt) Mercury is considered to be a metal, and conducts electricity extremely well. Perhaps that is what you were wondering. Perhaps you think it is NOT a metal. I think sodium conducts electricity and is used in Sodium Vapor lights which you often see in city streets. These are just my thoughts . See what others have to say.
Copper is often used as a material for the wire itself, but I don't think you would ever use a metal to insulate a wire. Metals all conduct electricity, meaning using them as insulators for anything electrical would be a very bad idea. The most common material used to insulate electrical wires is PVC (polyvinyl chloride).
Cork should be a poor conductor. Cork is a lite wood like, low density material. Often used to insulate heat, which is a clue. Things that are not good conductors of heat are normally poor conductors of electricity.
Insulator, or insulation, or non-conductive material. Wood, plastic and ceramic are examples of non-conductive material often used as insulators.
Metalloids, also called semimetals, have the characteristics of both metals and non-metals. Three characterics of metalloids are insulate, conduct electricity, and its elements are Silicon and Boron.
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
Aluminium hangers do conduct electricity, as aluminium is a good conductor of electricity. The reason you may not experience an electric shock when touching an aluminium hanger is because it is often coated with a non-conductive material, such as paint or plastic, which prevents direct contact with the aluminium.
Old houses are hard to insulate because they were built without insulation in mind and often require major work - like knocking down walls and similar.
They are a good conductor of heat and electricityThey are often shinyThey are ductilethey are malleableProperties of metals include the fact that they are generally shiny, malleable, and hard.
