Foam is a good insulator because air is not that good at conducting (meaning that it doesn't easily transport heat or cold) in relation to other materials. As foam consists of many tiny plastic pockets trapped with air it both stops convection and prevents conduction.

Is a foam cup A good conductor of heat?
It is a good insulator of heat :)
How is a foam coffee cup a good insulator?
The foam contains air, which is a poor conductor of heat.
Is a foam coffee cup a conductor or a insulator?
Styrofoam, along with most other expanded plastics, is a very poor insulator of heat and electricity, thereby making a foam coffee cup a very good insulator.
Examples of good heat insulator?
styrofoam ,bubble wrap ,polyurethane foam, fleece ,aluminiaum.
Is plastic a good insulator of heat?
yes i think A2: No, Not in Solid form. It is a Very Good insulator If sprayed into closed-cell foam or spun into fabric.
Which material Is the best heat insulator?
The best insulator of heat is probably polystyrene foam or fiber glass.
Whether plastic foam which contains pockets of air would be a good conductor or a good insulator.?
Because it fills heat slowly
Is sponge a good heat insulator?
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
Why does metal feel cooler than foam?
Metals are good heat conductors, so the extra heat is drawn away from the warmer area (your hand) to the cooler areas. Foam is a heat insulator, so the heat won't travel away as fast.
Is foam a good conducter of heat?
In a foam there is a large gap between the conduction band and the valence of band in the atoms makng up the foam. If any object is to conduct electricity through it the gap between the conduction band amd the valance should be minimun or overlapping so that the electrons in the valance band can go into conduction band and conduct electricity
Is black foam a good insulator?
Polystyrene foam is a good insulator. The characteristics that make polystyrene is a good insulator stems from its composition of long polymer chains and because it encapsulates regions of gas in the form of a closed cell foam. Air and gas in general are poor conductors of hear when convection is inhibited as it is in a foam. (The form used in insulation is often a closed cell foam, but that is not the only form taken by polystyrene.)
What is a good insulator for heat?
Either a vacuum (thermos bottle) or air that can't move ... which is just what foam insulation is (tiny bubbles).
