It is usually a material that has no free electrons in its out valance rings. This condition makes it hard for free electrons to move from one atom to another atom easily. Without this movement of electrons the material is classed as an insulator. Easy movement of electrons from one atom to another is classed as a conductor the very opposite of an insulator.
In the electrical field, the purpose of any insulating material is to separate electrical conductors without passing current through it. Material like PVC, glass, asbestos, rigid laminate, varnish, resin, paper, Teflon, and rubber are very good electrical insulators. Insulating material is used as a protective coating on electrical wire and cables.

What fabric is a good insulator wrapped around a jar?
If you use a glass jar, it is already an insulator
Is plastic a good insulator of heat?
yes i think A2: No, Not in Solid form. It is a Very Good insulator If sprayed into closed-cell foam or spun into fabric.
Substances that are poor conductors of heat?
After the published tables the silica aerogel is a very good thermal insulator.
What makes an insulator insulate?
A material that insulates, especially a nonconductor of sound, heat, or electricity. A device that insulates another material or space from something. For instance glass is a good insulator from electricity. The electrons will not flow through glass. Cork is a good insulator from sound. Sound waves have a hard time passing through cork. Wood is a good insulator from heat.
Is the element neon a good conductor of heat and electricity?
Neon is a good insulator due to its stable electron structure. Insulator acts as a barrier to electrons. Neon is used in bulbs.
Is sponge a good heat insulator?
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
Which is an example of a good 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.
Is foam a good insulator or conductor?
insulator
