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.
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

Some plastic are good insulator's, such as Polystyrene ( Styrofoam). It should also be a good thermal conductivity.
yes some are
but some plastic are not good
because in plastic the bonds are tightly bound and such results in tightly bound electrons hence no free electrons and no passage of electricity.
because it can hold all the air inside it once it is locked or sealed.
If it is made of metal, it is a conductor. If it is wooden, it is an insulator.
bowl is conductor
Plastic is an insulator. Yes, he is correct!
An example of a good insulator of electricity would be rubber. An insulator is anything that does not conduct electricity and as such offers protection from direct electric current.
It is an insulator. It would take many wraps to make it become a good insulator. There are much better products in the market place to use for insulation purposes which are much safer.
Plastic is an insulator.
yes plastic is very good insulator
A good insulator would be rubber or plastic.
It seels it the best.
A good insulator for electricity would be plastic, rubber, glass and ceramic. Hope this helps!
Because plastic is a good insulator from heat & electricity.
Plastic is a non conductor of electricity.
the best insulator is plastic. a better insulator is rubber which is used for wires and other electrical lines
If it is made of metal, it is a conductor. If it is wooden, it is an insulator.
as plastic is a good insulator of electricity.
Plastic is an insulator.
