Is aluminum foil insulation materials easy aging?
The use of aluminum and high surface reflection characteristics of multilayer aluminum surface reflection can be achieved completely block heat radiation purpose. But through the aluminum surface between the air and the like are still A small amount of convective heat transfer. If you require complete insulation, available multilayer vacuum aluminum reflective insulation structure.
Just use little water vapor in the environment, not long-term high temperature, such as near the melting point of aluminum, usually you do not have this aging said. Aluminum foil can be used for thermal isolation at high ambient temperatures.
Is usually not easy aging, aluminum foil has good gas barrier and light barrier effect. But depends on the environment of use, aluminum foil Insulated material is usually complex, not just aluminum, the center may also have a sandwich, the key is to see what the sandwich material.
