For practical purposes, air is an excellent thermal insulator. So any material with lots of entrained air (and through which the air cannot freely pass) will be a good thermal insulator.
The remaining conduction path through the material is along the filmy walls of the bubbles, and this path will be long and of small cross-section.
A vacuum is of course a better thermal insulator, but there are practical difficulties in making a foam of vacuum bubbles.
And there are some materials (some CFC gases) which are better thermal insulators than air, but once again there are difficulties in keeping these gases entrained in the foam bubbles.

Why is plastic an insulator?
Plastic is an insulator meaning it does not conduct heat .
Is plastic a heat insulator?
no
Is styrofoam a better insulator of heat than plastic?
Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
Is plastic an insulator of heat?
yes it is.
Is plastic a insulator of heat?
Yes
What is a material that does not conduct heat or electricity well?
An insulator.
Is a toothpick a conductor or a insulator?
If the toothpick is made of wood or plastic, it would act as an insulator.
Why are plugs made out of plastic?
Because plastic is a good insulator from heat & electricity.
Is a plastic bag a conductor?
No, because plastic is an insulator making it a very bad conductor of heat.
Why are the plug sockets covers made of plastic?
Because plastic is a good insulator from heat & electricity.
How does a plastic box help to reduce heat loss?
Plastic is an insulator therefore it is a poor conductor of heat. A plastic box will therefore be able to keep a lot of heat on the inside.
