8011 aluminum foil for semi-rigid duct
8011 aluminum foil is currently the best industrial packaging material in the world, and is widely used in building roofs, walls, ceilings, ventilation ducts, etc. 8011 aluminum foil has excellent properties, such as light weight, low thermal conductivity, good heat resistance, aging resistance, and easy use. Compounded with other materials, there are no droplets during the combustion process. It can also be used as an insulation material for doors and windows. The aluminum foil actually conducts the external temperature to protect the internal temperature from external influences. In fact, thermal insulation cotton has the functions of heat preservation, waterproof and moisture proof. Its solar radiation absorption coefficient is extremely low and can isolate most of the heat.
