The hydrophilic aluminum foil helps to increase the heat exchange rate by 5%. There are 10 key parameters of the converter foil. Welcome to learn more about aluminum fin stock.

The hydrophilic aluminum foil has strong hydrophiicity. It can be used in air conditioning to optimize the ventilation effect of the heat exchanger, thereby increasing the heat exchange rate by 5%.

In addition, the aluminum fin stock also has other advantages such as anti-corrosion, bacteria resistance and no odor. It is mainly used in high-end air conditioner, refrigerators, automobile air conditioners and automobile water tanks. Welcome to know its properties through the following table.

Item of converter foil	Technical parameter
Film thickness	1.0-20 µm
Hydrophilicity	Initial hydrophilic angle ≤10°, continuous hydrophilic angle ≤20°
Adhesion	Erichsen test(5 mm deep):no flaking, no delamination
Corrosion resistance	RN≥9.5(72 hours)
Alkali resistance	The coating is completely no bubble after being immersed in 20% NaOH at 20℃ for 3 minutes
Solvent resistance	Sample weight loss ≤1%
Heat resistance	At a temperature of 200℃ for 5 minutes, its performance and color are unchanged. At a temperature of 300℃ for 5 minutes, the coating film is a little yellowish.
Oil resistance	The coating is without bubble after a 24-hour immersion in volatile oil.
Odor	Odorless
Wear on the mold	There is less wear on the mold.
