Rubber, Styrofoam, air pockets, cloth, plastic
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 nonmetal would make a good insulator.
It is an insulator!!
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.
Trapped air makes a good insulator.
Freely moving electrons make materials more conductive, and less insulating.
Nichrome
Often you can make a material change state by heating or cooling it
Steel :)
No shared electrons between neighboring atoms/molecules in the material makes for a good electric insulator.A good thermal insulator has lots of air or gas (which insulates) trapped in the material.
