They are polysterene foam and fiber glass (not encouraged due to irritation of the skin when broken). Also you can use Styrofoam and sawdust. tin foil is useful because it reflects the light, but if it is making contact with the ice cube then it just makes it melt faster.
The Answer: Alcohol
The ice begins pulling heat (energy) from the alcohol.
It is not the ice cooling the alcohol it is the alcohol that transfers heat to the ice (solid water). The ice draws heat from the warmer alcohol inducing the ice to melt. This is because the freezing point of the alcohol is much lower than the ice. If we were to keep the ice in the glass (by adding more) the rate of melting of the ice would slow because the heat (energy loss) of the alcohol has been reduced. But it would indeed continue to draw heat from the alcohol just more slowly. {this of course would require no atmosphere heat (energy) from contacting either the ice or the alcohol.}
If we had solid CO2 (dry ice) it could draw enough energy (heat) from the alcohol to freeze it solid. {this of course would require no atmosphere heat (energy) from contacting either the ice or the alcohol. Plus a lot of dry ice to replace what has melted or sublimated away.
Great question! As a foam cooler manufacturer, we have a lot of experience and hundreds of stories by regular Joes who swear up and down that their reasonably-priced, thick wall Expanded Polystyrene (EPS) foam coolers are better at keeping ice and drinks and food cold over a given number of days than hard shell coolers. As an example, I personally took a LoBoy thermal ice chest foam cooler on a camping trip in the Florida heat this past weekend. Left the driveway on Thursday with everything already iced down and come Sunday when I pulled the RV up to the dump station in preparation to head home, I dumped the remaining contents of the cooler and you know what most of it was? That's right - cold, chilly ICE.
Imagine it. A quality thick wall foam cooler or thermal ice chest can literally keep ice cold for DAYS, not just hours. I'm not talking about cheap, flimsy so-called styrofoam coolers that you get for a dollar off the shelf, but a real EPS foam cooler with at least 1" wall thickness. To get the same level of thermal protection from a hard shell cooler requires more thickness. Here's why...
EPS Foam Coolers vs. Hard shell CoolersThe typical "Hard Shell" wall is a sandwich of polyurethane foam between an exterior of High Density Polyethylene (HDPE) an interior of Polypropylene (PP).
HDPE has a thermal conductivity 14 to 17 times higher than EPS. PP has a thermal conductivity 3 to 7 times higher than EPS. Thermal conductivity is the rate which a material transfers heat. HDPE and PP also retain the absorbed heat longer.
EPS and polyurethane foam have similar thermal conductivities. Wall thickness then becomes the determining factor.
How well the lid seals also affects thermal performance of the cooler.
So, when you want to have superior thermal protection for keeping ice cold for days and not just hours - and when you want to spend far less money but still get yourself a cooler that will last you YEARS, then you'll want to get a thick wall foam cooler (again, not a flimsy 'entry level' cooler that people just throw away) like the kind LoBoy makes.
But here's another thing that's important to consider. People have had the impression for years that foam coolers are a disposable product. That's not the way it's supposed to be, but because some manufacturers have been making inferior, flimsy foam coolers that leak and fall apart after one or two uses, hundreds of thousand of otherwise recyclable material ends up in the trash or as litter in the environment, and that's just not right.
EPS Foam Coolers are totally recyclable. LoBoy runs a 100% EPS Foam Recycling program because we care about the environment, and what's more, we make superior foam coolers and shipping coolers so that they last for many, many years. That way, people save money, there's less energy consumption, and customers aren't frustrated by broken, leaky foam coolers.
So, if you want to have better thermal protection for your ice - to make it last for days - and if you want to buy a foam cooler that lasts for years and from a green company that actually cares about the environment, think LoBoy EPS Foam Coolers.
okay so i think lika maybey babay styrofoam, bubble wrap, tinfoli, steel
Styrofoam is the best material for insulating ice because of its chemical structure and make up. That is why styrofoam coolers are so popular.
There are many materials with good insulating properties. Bubblewrap is a good one for ice.
In clothing, gortex, wool, and down are all good insulators. In construction, fiberglass is very often used. Some green construction uses bales of hay as insulators.

Consider a drink with ice in it. Room temperature is warmer than the drink, so just by being in the room (or even worse, in your warm hand) the drink is going to absorb a certain amount of heat energy which tends to increase its temperature. However, any temperature higher than the melting point of water (0o Celsius) is going to melt the ice. And since it takes energy to melt ice, that energy cannot raise the temperature until the ice is all melted.
Permanet Magnet
It's due to the material in the salt that allows the ice's mass to lower. The temperature doesn't effect the process in a good way. Actually, it helps the ice melt more with the salt material.
Glacial till or 'Moraine'.

An insulated bottle keeps coffee hot by convection, radiation and conduction.
Yes, they are that's what keeps them wet
In a perfectly insulated container, the cold that is stored and contained in the Ice would have no where to dissipate to; therefore the ice must remain intact.
Ice and ice boxes (insulated boxes or cabinets in which a block of ice was set) were the norm for keeping items cold. The ice could keep for several days if the box was well insulated and well sealed.
Insulated Coffee mugs can be made from many materials, the inner layer is usually made from stainless steel while the outer while can be either stainless steel or plastic. The vacuum design however is what keeps your coffee hot compared to a ceramic coffee mug
An insulated, temperature controlled chicken barn.
They work in the same way that wetsuits do, just in reverse. The insulated wetsuit material keeps in the cold, without letting any warm outside air reaching the can, proloning the cold temperature of the drink.
The best way to preserve ice is to keep it in an insulated space. Coolers and freezers are the best places to store ice to preserve it.
It is a Medical material shipping form that you use to label boxes that contain dry ice. The dry ice inside keeps the medical material frozen.
yes, but its probably better to store it in a simple insulated cooler; it will last longer in an insulated cooler than in the fridge.
Insulated grommet curtain panels can be dyed, but care must be taken so they dye evenly.
insulated bag that you provide, then paper and plastic is last
