It is a substance with a low conductivity.
A Perfect Insulator is not possible. However Rubber has a conductivity ~ 10^-40

A material which is a poor conductor of a particular type of energy.
This could be thermal energy (heat), electrical energy, sound, even nuclear. Not all materials which are good insulators to one type of energy are good at insulating others. However, most heat insulators are also good sound insulators because the mechanics of conductive heat transfer and sound transfer are the same, involving molecular collision.

A more broad definition of an insulator is a barrier that resists conduction.
It applies to the transmission or lack thereof of transfer of energy, often in the form of waves.
Common types of insulator are electrical, sound and thermal but in a really broad sense the glass of a home aquarium is an insulator. It keeps the fish and water in and air out.

Insulator - A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth, and rubber are good electrical insulators. Feathers and wool make good thermal insulators.

An insulator is a substance which does not conduct heat/ electricity. Examples are glass and wood. The opposite are conductors, such as copper or other metals.

An insulator is something with a high resistance to the flow of electricity or heat.

Its a substance or mechanism that stops whatever you’re trying to insulate against. Wind, rain, heat, cold, etc.
An electrical cable is insulated with rubber, PVC, etc to stop the live conductor coming into contact with you, another conductor or component.

An insulator is something that has a very high resistance to the flow of electricity.
Copper has a low resistance and it is for this reason that copper is used in electric cables to conduct electricity.
The copper will be sheathed in a material such as rubber which has high resistance, is not a good conducter and prevents electric shock from the copper conducter contained in the sheath..
