It Isn't. At least, not in Solid form.
Plastic sprayed into a closed-cell foam, though, is an excellent insulator. Each "capsule" of gas or air is separated from each other by a miniscule cobvering of plastic; slowing heat transfer. Newer refrigerators have the foam sprayed in to fill all crevices.
The R-value will give you its efficiency: R-34 is twice as good as R-17, etc.

Is Styrofoam a good conductor or a good insulator?
Electrical or thermal? Either way, it's an insulator.
Which is an example of a very good insulator?
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.

An example of a insulator?
An insulator has several different meanings. The two most common are an electrical insulator and a thermal insulator. an electrical insulator would be polyethylene. a thermal insulator would be wool.

Is a glass a thermal insulator?
insulator. it is not a very good insulator though.
Is wood and plastic an thermal insulator?
No. Wood and plastic are two materials, not one.They can be insulators, or a composite made from wood and plastic could be an insulator but THEY cannot be ANinsulator.

the worst conductors of heat are wood, plastic, rubber, and cloth.
What is a very good thermal insulator?
oxygen.is the best insulator
Why saucepans have plastic handle?
Because the plastic handle act as a thermal insulator, to avoid burns on your skin.
