Yes, polymers can be good insulators because they have high electrical resistivity compared to metals. This property makes them useful in applications where electrical conductivity needs to be minimized, such as in the insulation of electrical wires or in electronic components.

Is shiny a good insulator?
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.

Is a marble a good insulators?
Marbles are not good insulators because they are made of dense material and can conduct heat easily. Insulators are materials that do not allow heat to flow through them easily, whereas marbles are more likely to transfer heat.
How is sound insulator similar to and different from a heat insulator?
Sound insulators are similar to heat insulators in that they both aim to reduce the transfer of energy, but they work in different ways. Sound insulators absorb and dampen sound vibrations, while heat insulators reduce the transfer of heat through conduction, convection, or radiation. Materials that are good sound insulators may not necessarily be good heat insulators and vice versa.
Materials that are not good conductors or and not good insulators are called?
Semiconductors. They have conductivity between conductors and insulators and are used in electronic devices like transistors and diodes.
Why are plastic good electricity insulators?
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.
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
What are some good insulators?
plastic, paper, wood, cardboard, and rubber are all good insulators
Are diapers good insulators?
diapers are good insulators because they hold in the cold and and heat but is a bad conductor
List of good insulators?
Some materials such as "silicon dioxide or teflon" are very good electrical insulators. A much larger class of materials, for example "rubber-like polymers and most plastics" are still "good enough" to insulate electrical wiring and cables even though they may have lower bulk resistivity. These materials can serve as practical and safe insulators for low to moderate voltages (hundreds, or even thousands, of volts)."
