Here are some details about vacuum flasks: How they work: Vacuum flasks have a double-walled construction with a vacuum between the walls. This vacuum prevents heat transfer by conduction and convection. The walls are often silvered to reflect radiant heat, further reducing heat loss or gain. Typical Use: They are used to keep drinks hot or cold for several hours. Materials: They are typically made of metal, borosilicate glass, foam, or plastic. Common Names: Vacuum flasks are also known as thermos flasks or Dewar flasks. Time: The product can hold liquid heat above 42°C for up to 6 hours and liquid cooling below 10°C for up to 5 hours.
