An insulator is a material that does not allow electricity to pass through it. Insulators have high electrical resistivity, preventing the flow of electrical currents. Examples of insulators include rubber, plastic, and glass.
Rubber, glass, plastic, wood, and ceramic are common materials that are insulators. These materials have high resistance to the flow of electricity, making them suitable for insulating wires and electrical equipment.

The name of the material that does not transmit heat or electrical energy is an insulator. Insulators have high resistance to the flow of heat or electricity, making them useful in applications where preventing the transfer of these forms of energy is desired.
Insulators in electricity can be glass or ceramic.Insulators in heating can be polystyrene or fibre panels.
Enorder for materials to conduct electricity they need to have free electrons which carry the current. Materials which can do this include metals, water, Ionic salts when in there molten or aqueous states. Wood, plastic, gases and covalent compounds do not have free electrons and therefore do do conduct.
Insulators are materials or substances that do not readily allow the passage of sound or heat. Two examples of insulators are glass and porcelain.
Insulators in electricity can be glass or ceramic.Insulators in heating can be polystyrene or fibre panels.
The general name given to nonconducting materials is insulators. Insulators do not allow electric current to flow easily through them due to their high resistance to the flow of electrons. Examples of insulators include rubber, plastic, and glass.
Electricity is the flow of charged particles (often electrons), hence it flows easily where there are many 'spare' electrons (as in transition metals). An electrical insulator is something that does not have very many of these, for example the group 8 elements have a full outer shell, no electrons are 'free' as this process requires. Plastic insulates electricity.
