Copper and a Styrofoam
Two examples of electrical materials that are insulators are rubber and glass. Insulators are materials that do not conduct electricity well and are commonly used to protect against electrical shocks or to prevent the loss of electrical energy.
Two bad insulators are metals (such as copper and aluminum) and water. These materials allow electricity to flow through them easily, making them poor choices for insulating against electrical currents.
Electric insulators are materials that do not conduct electricity easily, meaning they have high resistance to the flow of electrical current. Some common examples of electric insulators include rubber, glass, plastic, and ceramics. Insulators are essential in electrical systems to prevent the loss of electrical energy and to protect against electrical hazards.
The two main insulators of heat are air and materials with low thermal conductivity, such as wool or fiberglass. These materials slow down the transfer of heat by trapping air pockets or creating barriers that prevent heat from moving through them easily.
Rubber and plastic are examples of materials that are insulators. They do not conduct electricity well because their electrons are tightly bound, making it difficult for them to move freely and carry an electric charge.

"insulators"
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.
Depends on the kind of plastic, but most are.

Some heat insulators are fiberglass, polyurethane foam, and polystyrene. Two other thermal insulators used as insulating materials in building construction are mineral wool and cellular glass.
