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 other materials that are poor conductors of electricity and good insulators are rubber and glass. Rubber is commonly used in electrical cords and cables due to its insulating properties, while glass is a common insulator in electronics and construction materials.
Two types of insulators are plastic (such as PVC or rubber) and glass. Insulators are materials that do not conduct electricity easily, making them useful for electrical applications.
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.
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.

Insulators are materials or substances that do not readily allow the passage of sound or heat. Two examples of insulators are glass and porcelain.

Two good Insulators are foam and styrafoam
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.
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.
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.
Conductors are materials that will allow electricity to flow through them. Materials that contain 1, 2, or 3 valence electrons are good conductors. Some examples of good conductors are gold, silver, aluminum, and copper. Insulators are materials, or combinations of materials, with a high number of valence electrons (5, 6, 7, and 8). Examples of good insulators are porcelain, glass, air, and rubber.
heater and portable barbecues
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.
