Some aluminium foil products produce a smell when heated?

Some aluminium foil products produce a smell when heated, for example today we will look at the smell emitted by aluminium foil tape and the tin foil chimney on the top of a water heater when heated. Is the very pungent smell emitted from the tin foil chimney on top of a water heater's heat exhaust toxic to humans? Let's explore this together!

First let's see, does aluminium foil tape smell when heated? Yes, aluminium foil tape has a smell when heated. Aluminium foil tape will smoke and emit an odour when heated, so be careful not to inhale it. Aluminium foil tape is made of high quality pressure-sensitive adhesive, with good adhesion, strong adhesion and much improved thermal insulation properties. Aluminium foil tape is used in conjunction with all aluminium foil composite materials for seam adhesion, sealing of insulation nail punctures and repair of breaks. It is the main raw and auxiliary material for refrigerator and freezer production plants, and is also a necessary raw material for the insulation material distribution department. It is widely used in refrigerators, air conditioners, automobiles, petrochemicals, bridges, hotels, electronics and other industries. It can also be used for PDA, PDP, LCD monitor, laptop, copier and other electronic products where electromagnetic shielding is required.

Secondly, the tin foil chimney on top of the water heater that dissipates heat and exhaust will also give off a very pungent smell when heated. So why does this smell occur? Is it toxic to humans? The smell is caused by the substandard material used for the expansion flue pipe. The smell emitted by substandard materials when there is a drastic change in temperature is most of the time harmful to the human body, it is recommended to open the windows and doors for ventilation, after the water heater has been in use for some time the smell is still there, you should consider replacing the metal exhaust pipe.
