Detail explanation:

The effect of hydrophilicity

Aluminum foil surface with hydrophilic layer has a strong affinity for water, condensate on the fins spread quickly, not easy to form a "water bridge", so the ventilation effect of air conditioning operation works well. A measure of hydrophilicity is called a hydrophilic angle. Please find the comparison between ordinary aluminum foil and hydrophilic aluminum foil in the following table.

Coating types:

(1)Film with corrosive resistance inorganic resin

(2)Hydrophilic film: organic resin


Characteristic of hydrophilic aluminium foil

  • excellent hydrophilicity and corrosion resistance
  • good formability and no wear on the mold
  • a strong resistance to stamping oily, soluble, heat resistance
  • air flow resistance, heat exchange rate can generally increase 10% -15%.
