Detailed explanation-1: -Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Detailed explanation-2: -Rubber. Rubber is a tried-and-true material in electrical insulation. Most electricians wear rubber gloves to protect them against electric shocks, and protective rubber electric mats are often found in front of fuse boxes and switchboards. Silicone rubber is often found in electrical insulation and wire sheathing.

Detailed explanation-3: -Insulators are materials whose atoms have tightly bound electrons. These electrons are not free to roam around and be shared by neighboring atoms. Some common insulator materials are glass, plastic, rubber, air, and wood.

Detailed explanation-4: -Rubber is an electrical insulator. This material’s molecular structure comprises localized electrons, which don’t move. As a result, they cannot transfer electric current to nearby electrons, making rubber a non-conductor.

Detailed explanation-5: -Rubber is known to be an insulator because rubber can limit the transfer of electricity. The rubber properties prevent the electrons to be able to freely move and the addition of the electrons being tightly bounded makes rubber a good insulator .
