No material exists that doesn't conduct electrical charges at all. We call materials that conduct electrical charges poorly insulators; a material that didn't conduct electricity at all would be a perfect insulator.

Electric insulators
Expressed that way, it is somewhat confusing. The difference is how well they conduct electrical currents.
In electricity, Insulators help insulate electric charges. Conductors conduct the electric charges and make them into electricity.
Insulators are materials that don't conduct heat well, or (for electricity), materials that don't let electricity pass through them. In general they are non-metallic materials.
The substances that do not conduct electricity are called electrical insulators while those which conduct electricity are called conductors.

Anything that isn't a conductor. Insulators don't conduct charges very well because their electrons cannot move freely.
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.
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.
The general term for "materials that conduct heat poorly" is "insulators". Examples would be wood, many ceramics, and cloth such as wool or cotton.
We use the term insulator, specifically electrical insulator, to refer to an object or material that does not conduct electricity to any significant degree.The term insulator, with no other explanation, is assumed to refer to electrical insulators. There are of course other materials which are used as insulation for heat. They provide thermal insulation and may or may not conduct electricity.
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
An electrical insulator is an object that's internal charges do not move freely. This makes it nearly impossible to conduct electricity. Some examples of insulators are, Styrofoam, most plastics paper, glass, and rubber.
