An insulator or a dielectric is the generic name for a material which does not allow electrons to flow through it. Many polymers such as PE, PP, PVC etc are insulators. Ceramics such as hardened clay are also insulators. Others include:
- glass
- rubber
- bakelite
- oils
- phosphorus
- sulfur
- wool
- silicone rubbers
- silicone oils
- Teflon
- nylon
- polycarbonate
- acrylic
- abs
- etc.
Such materials are insulators. Insulators are materials that don't have free electrons available for the flow of electrons, which is called an electric current.
Insulators are either pure elements which have a "full" outer electron shell (containing 8 electrons, which makes a full set for the shell) or they are compounds that have their electrons completely bound, with none available to flow away in a current.
Further notes:
All insulators can have their outer shell electrons broken loose if a high enough voltage is applied. This is called the dielectric breakdown voltage.
"Conductors" are elements that have only 1 or 2 electrons in the outer shell. These elements' electrons are loosely bound to their atoms and are already moving around in the crystalline structure. The application of a voltage to a conductor will cause these electrons to flow from negative to positive. This flow is what is called the current.

Which element has a crystalline lattice through which electrons flow freely?
calcium
What is a layer of rock that does not allow water to flow through called?
the impermeable layer
What is the definition for electrical energy?
Energy made available by the flow of electric charge through a conductor.energy resulting from the flow of charged particles, such as electrons or ions:)energy resulting from the flow of charged particles, such as electrons or ions
What material will allow electricity to flow between the battery and the light bulb?
Any conductor like copper or silver or aluminum
How does a voltage cause current to do work?
A voltage will cause electrons or other charge carriers to flow (if there is a path through which they can flow). In other words, it will cause a current.
What is a material that allows electrons to flow easily through it?
Anything that is classified as a conductor will allow the flow of electrons.
Electrons do not readily flow through what material?
The material that electrons do not readily flow through in the electrical trade is classed an an insulator.
What is the difference between a electrical conductor and a electrical nonconductor?
Simply put an conductor is a material that lets free electrons flow through it. When free electrons are flowing that is called current. So an electrical conductor will have current pass through. Non-conductive material will not allow these electrons to flow and no electricity can be passed through. Good conductors have almost no resistance to electron flow.
Why does nonconductive material allow the flow of electricity?
If you mean "dis"allow the flow, it's because electrons cannot travel easily between the atoms of the material.
How does an electrical insulator work?
Any material that does not allow the free flow of electrons.
What is the measurement of how difficult it is for electrons to flow through a material?
Resistance.
What do you call a material that electrons will flow through freely?
conductor
What material is most difficult for electrons to flow through?

What is a material through which electrons do not easily flow?

What materials allow electricity to flow freely?
Because of freely moving of electrons in the material
