Are plastic thermos safe
Thermos lids are perfectly safe, despite the alarmist answers already written. They're almost universally made from Polypropylene, a polymer that has had virtually no bad press for decades. Plastics have made the world a far safer place than if we had never invented them.
Is stainless steel good for thermos
Bottles made of stainless steel have several advantages, including being light and strong while providing excellent thermal insulation and being resistant to corrosion, extrusion, and heat.
How do I choose a good thermos
A good thermos should have excellent hot and cold retention. It should never leak, be convenient to use and carry, and be easy to clean, not retaining residual flavors or odors from drink-to-drink.
Why is metal good for a thermos
Stainless steel has better insulation and impact resistance than glass because its alloy elements improve hardenability and strength. While a glass thermos has greater heat retention properties, it is often more fragile and prone to damage.

What materials are better insulators for a thermos
Results: It was found that the aluminum foil and cotton were the best insulators for keeping the water cold while the Styrofoam sheets and the bubble wrap were the worst two insulators for keeping the water cold.
Which is better thermos flask or stainless steel flask
A thermos is similar to a vacuum-sealed container, as it seals between the layers. It keeps hot beverages at a stable temperature for the user to enjoy for longer. A flask is a metal or glass container with a narrow neck and is typically used for secretly storing a small amount of alcohol.

Does plastic release toxins when heated
Research suggests that all plastics may leach chemicals if they're scratched or heated. Research also strongly suggests that at certain exposure levels, some of the chemicals in these products, such as bisphenol A (BPA), may cause cancer in people.
At what temperature does plastic release BPA
Higher temperature at 70 °C induced significant release of Sb and BPA. Release of Sb and BPA increased with storage duration up to 4 weeks.
Is it safe to drink hot drinks in stainless steel
Stainless steel is a non-toxic material that doesn't need a liner. It's a metal that doesn't leach chemicals, even if the bottle becomes damaged or if you fill the bottle with boiling liquids like tea and coffee.
