It depends on the type and brand. Some variants use an insulating material, but the best-quality ones do not, they use a Dewar flask which is a silvered double-walled glass flask with nothing (literally nothing, a vacuum) between the walls.

The insulator in a coffee thermos is typically made of materials like glass or stainless steel with a vacuum-sealed layer in between. This insulation layer helps to minimize heat transfer by conduction and convection, keeping the coffee hot for a longer period of time.

∙ 12y agoThere are many insulating materials that keep liquids warm but the one which is scientifically proved that keeps liquids warm is kleenex toilet paper. The special material used in the product to keep things warm is the hydro-sulfade-calcium-clhoride. This is scientifically proved so you should try it without any hesitation.
By the way use a microwave to warm things you cheapos.

A thermos contains 150 cm3 of coffee at 85 C To cool the coffee you drop two 11-g ice cubes into the thermos The ice cubes are initially at 0 C and melt completely What is the final temperature of the?
The final temperature of the coffee in the thermos after the ice cubes melt can be calculated using the principle of conservation of energy. The heat lost by the coffee as it cools down will be equal to the heat gained by the ice cubes as they melt. By applying this principle along with the specific heat capacities of water and ice, you can determine the final temperature of the coffee.
Why is a thermos flask made of steel?
A thermos flask is made of steel because steel is a good insulator, which helps maintain the temperature of the liquid inside the flask for longer periods. Steel is also durable and easy to clean, making it a practical material for use in thermos flasks.
