Aluminium foil roll is a hot stamping material that is directly calendered into thin sheets with metal aluminum. aluminum foil is more and more widely used, and the thickness of aluminum foil is also different for different purposes.What are three physical properties of aluminum foil ?
Reflection properties
Aluminum foil can reflect 98% of light and infrared. The bright surface also has low heat emissivity. This helps to save energy during the barrier process. Its insulating function extends to fire protection. In the "firewall" of vehicles and ships, as well as in fire doors and building panels, aluminum foil can dissipate heat and prevent the oxygen needed to initiate a flame.
Conductivity properties
Aluminum foil has a completely effective buffer function for magnetic and radio frequency radiation. In fiber optic cables, aluminum foil acts as a "tracker" to test the integrity of the cable connection. In the cable packaging, the electrical conductivity enables the integrity of the cable circuit to be verified.
Insulation properties
There are many cases regarding the effectiveness of aluminum foil as an insulator. A finned heat exchanger made of aluminum foil gives every modern car a cooling and heating function. In addition, it can reflect 98% of light and infrared. The bright surface has low heat emissivity, which helps to save energy. Another kind of heat insulation is fire prevention-the "firewall" of vehicles and ships, fire doors and building panels, etc. Aluminum foil can dissipate heat and prevent the oxygen needed to start the flame.
