It is not a good insulator if you are dealing with temperature because of the air pockets and the temperature of air inside a bubble (air pocket) but it would be a good insulator if your dealing with something related to circuits because plastic is not a conductor.
bubble wrap is a good insulator because the little pockets of air trap the heat/don't let heat through. this also is the same for keeping things cool.
Air bubbles.
Depends what you are insulating against but bubble wrap can be good a insulating.
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.
Bubble wrap is better because it contains air, which is a very good thermal insulator.
styrofoam ,bubble wrap ,polyurethane foam, fleece ,aluminiaum.
Tin foil is not a thermal insulator and so is irrelevant to the question.Bubble wrap is a better insulator at low temperatures but as the temperature increases bubble wrap will simply melt and provide no insulation at all.
You can't stop it, but you can slow it down. 1. Put a lid on the cup. 2. Wrap it in a good insulator such as bubble wrap.
Bubble wrap. Aluminum is a good conductor of heat and will help the temperature equalize. Bring to room temperature. Bubble wrap is an insulator and insulating. The trapped air space in the bubbles work like the insulation in your attic. It is basically REAL BIG foam insulation.
Bubble wrap is made up of many small pockets of air. Air is a relatively poor conductor of heat, it mostly transfers heat via convection (movement of the heated air). The bubble wrap prevents the air surrounding the object from convecting because it is trapped in the bubbles. This reduces the amount of heat which can be transferred to/from the object, thus insulating it.
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
tin foil
No, glad wrap is not a good insulator. There are other materials used in which are much better at insulating than glad wrap, such as aluminium foil or wool.
