Hydrophilic painted aluminum foil is commonly used in air conditioning systems for heat exchange purposes, usually using 1100 aluminum foil or 8011 aluminum foil. Because of its excellent formability, corrosion resistance and thermal conductivity, these properties are critical for efficient heat exchange in air conditioning systems.

Features of hydrophilic painted aluminum foil:
1. Excellent hydrophilicity and corrosion resistance
2. Good formability and no wear on the mold
3. Extremely strong resistance to stamping oil, solvent resistance and heat resistance
4. The air flow resistance is small, and the heat exchange rate can generally be increased by 10%-15%.
4. Green and environmentally friendly
Hydrophilic painted aluminum foil has many excellent properties and has broad application prospects in many fields such as refrigeration equipment and food packaging.
