A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.
Plastics are a good electrical insulators because they are insulators. Electricity could not pass through them unlike copper. Another good example of insulators is rubber.
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
plastic, paper, wood, cardboard, and rubber are all good insulators

No, shiny surfaces are not good insulators. Shiny surfaces are reflective and do not support the absorption and retention of heat, which is a characteristic of good insulators. Good insulators are materials with low thermal conductivity that trap heat effectively.
They are called insulators. Rubber is an example of a good electrical insulator.More:PlasticGlassAirWoodCeramicPorcelainPaperVarnishMineral OilSlateMarblePolyethyleneSiliconePVCKaptonTeflon
