Two good Insulators are foam and styrafoam
Insulators are made from materials with insufficient charge carriers to support conduction. Practical insulators are made from ceramics, paper, plastics, oil, etc.
The lack of free electrons in the material that the insulator is made from is what makes an insulator insulate.
Rubber.
The poorest insulator would be the best conductor, which is one of the noble metals. Bakelite is a fairly good insulator, not too long ago electrical fittings were made from it.
First AnswerYes it is and it can also withstand heat. For many years mica was used in toasters to make a framework to hold the heating elements.Next AnswerActually mica is a very good electrical INSULATOR, but is a good THERMAL conductor, which is why it was used for holding heating elements.
A candle in not in the electrical classification category as being used for an insulator.
is foam dirt an metal a good insulator
Very low. It's used as an insulator.
Rubber.
yes copper is a good eletrical insulator
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
Electrical or thermal? Either way, it's an insulator.

Yes.
No! Its an excellent conductor.
rubber
An electrical insulator is a material whose internal electric charges do not flow freely. Rubber, glass, paper, and Teflon, which have high resistivity, are very good electrical insulators.
the best insulator is plastic. a better insulator is rubber which is used for wires and other electrical lines
It is a good electrical insulator because it has no mobile electrons, unlike metals which have a populated conduction band.
