Why is plastic a good insulator?

Answer 1

Well I am no scientist but my best guess would be because the fibers of plastic are woven so tightly that it holds in the heat better. Like the difference between a quilt and a afghan. One is basically more solid keeping you warmer. More space between particles and the more heat that escapes.

Answer 2

of a plastic

that has poor thermal conductivity. When blown into a foam, the gas

pockets within the foam are tiny bubbles

which are in contact with each other but not connected so that

convection currents can be established. The result is a very good

thermal insulator that enables one to hold a very hot drink only a few

millimeters from one's fingers and just barely feel the warmth of a plastic

Answer 3

Some plastic are good insulator's, such as Polystyrene ( Styrofoam). It should also be a good thermal conductivity.

Answer 4

yes some are

but some plastic are not good

Answer 5

because in plastic the bonds are tightly bound and such results in tightly bound electrons hence no free electrons and no passage of electricity.

Answer 6

Because it is hollow, and reflects most sound and absobs little. it is flexible, tough and effective to use for ear defenders...

Answer 7

because it can hold all the air inside it once it is locked or sealed.
