What is a polystyropoam ™ cooler?

What is popularly called styrofoam ™ Cooler is a container designed to keep food and drinks hot or cold for a longer period of time. Styrofoam ™ Cooler is commonly observed on picnics, beaches and in the garden, a popular choice for those who need a cooler because of its wide availability, disposable and cheap price. Traditional picnic cooler can often cost many times more than Styrfoam ™ cooler. Styrofoam ™ is the name of Dow Chemical Company for its brand of polystyrene foam. According to the company's website "there is no cup of coffee, cooler or wrapping material made of postyrophoam ™." While polystyrfoam ™ and the material used to produce ubiquitous coolers are made of polystyrene foam, they are actually composed of different polystyrene propotrums.

both polystyrene foam and hard coolers work by reducing the process known as heat transfer. Whenever two objects of different temperatures come into contact with each other, the heat is transferred from the warmer OBthe yek to a cooler object until the same temperatures are. This explains why there is a cold drink left outside, which eventually warms up to the room temperature. The heat of the environment is transmitted to a cold drink and increases its temperature.

essentially foam and hard picnic coolers keep things hot or cold because they prevent the heat or abandonment of the container. Items that are cool are thus maintained because the cooler prevents heat transfer to the container. On the contrary, items that are hot will remain hot because the cooler prevents heat from leaving.

polystyrene foam cooler works because polystyrene foam consists of up to eighty percent air. The foam air molecules reduce the amount of heat that can pass it. As a result, polystyrene foam is a poor heat conductor. The traditional picnic cooler has a vacuum layer between a section that holds food and outer shell. VaThe roof layer reduces heat transfer, keeps food and drink hot or cold. Thermal bottles work on the same principle.

Foam coolers are a popular option for many because they are cheap and easily accessible. However, polystyrene foam is easily damaged and foam coolers are not usually designed for long -term use.
