Ice is one of three states of water and natural forms when the water temperature drops below zero degrees centigrade, it is provided that is at atmospheric pressure.
There are different types of ice in terms of its structure, the most common structure of ice on earth is called hexagonal ice (lh acronym). The hexagonal ice is characterized in that ice crystals formed upon freezing the water molecules have hexagonal shape and also acquire a loose structure, which makes its density is much less than the liquid water, which causes hexagonal ice cubes float on water.
To retain the ice out of the freezer, it is necessary that its temperature never exceed zero degrees, at which ice would leave a solid state and cooling, which would lose its usefulness.
It is therefore essential to keep the ice in a cooler whose insulating properties are so high that they can preserve the state of freezing water for many hours, which will keep food and drinks as if they were inside a refrigerator in our house .
The best materials that can be made a cooler of quality are:
1. Outer jacket polyethylene grade A.
2. polyurethane insulation injected under pressure.
3. Seals mean elastomer material.
Polyurethane is an organic material having a foam and it is 100% non porous making it better in thermal insulation market. This material allows to keep the ice inside the refrigerator up to 10 days allowing to keep drinks and food cold during a tour of the hottest desert.
The most important characteristics of polyurethane are:
- High thermal insulating capacity and low heat transfer coefficient (better than other conventional materials such as cork, glass fiber or polystyrene).
- Continuous insulation, eliminating thermal bridges.
- Waterproof in water having no pores.
- Duration of its properties undefined in time.
- Total tightness.
