What are the main characteristics of aluminum foil?

Aluminum foil boasts numerous properties. Physically, it offers excellent thermal insulation. Aluminum foil's high reflectivity effectively reflects radiant heat, reducing heat transfer. It's commonly used for thermal insulation of high-temperature equipment, such as industrial furnaces and heat pipes, reducing energy loss. It also offers excellent moisture resistance, blocking water vapor penetration and protecting wrapped items from moisture. It's widely used in applications such as roof waterproofing and basement moisture-proofing. Aluminum foil is also flexible and can be bent and wrapped, making it easy to apply and adapt to various shapes, such as wrapping irregular pipes. Chemically, it exhibits a certain degree of corrosion resistance, resisting attack by some chemicals and suitable for environments with a risk of chemical corrosion. Furthermore, aluminum foil boasts excellent strength. Its fiberglass-based base imparts a certain degree of tensile and tear strength, allowing it to withstand certain external forces without breaking, ensuring stability and durability during use.
