Electricity cannot pass through certain materials. These materials are known as electrical insulators.
For examples:- plastic, wood, glass, and rubber....etc

Hey dear.....
Here is your answer....
Insulator :An electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors.
✔️A perfect insulator does not exist, because even insulators contain small numbers of mobile charges (charge carriers) which can carry current. In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms. This is known as the breakdown voltage of an insulator. Some materials such as glass, paper and Teflon, which have high resistivity, are very good electrical insulators. A much larger class of materials, even though they may have lower bulk resistivity, are still good enough to prevent significant current from flowing at normally used voltages, and thus are employed as insulation for electrical wiring and cables.
⭐EXAMPLES :
include rubber-like polymers and most plastics which can be thermoset or thermoplastic in nature.
.......... ALONE BUT HAPPY.......
Hope it helps you!!!!
