Question:

What's the maximum temperature that high temperature resistant aluminum tape resists?

What's the maximum temperature that high temperature resistant aluminum tape resists?

Answer:

Aluminum tape is made by calendering aluminum and thus an oxide of aluminum. The melting point of aluminum is 660.4℃ and its boiling point 2467℃. Aluminum foil can resist high temperature, but it can be oxidated. Aluminum oxide is an white power and belongs to covalent compound with the melting point of 2050℃ and boiling point of 3000℃.
As for aluminum tape, the aluminum foil can resist high temperature of 300℃ and most tapes can resist temperature of 300℃. Since aluminum is a good conductor of heat, wrapping the tape with aluminum foil does quicken the heat loss instead of heat preservation. Therefore, it's better to use heat-insulated cotton.
Aluminum foil is calendered by aluminum. Melting point: 660.37. Ignition point: 230℃. Since the boiling point is 100℃, the maximum temperature does not far exceed 100℃. Thus the maximum depends on the thickness of aluminum foil and sticking agnt.Fiberglass tape is also high temperature resistant. It can resist high temperature of 200℃ while the typical aluminum tape only -40℃-120℃.
