Product Description
Hydrophilic coated aluminum foil is a composite material based on aluminum foil. It has good heat dissipation properties of ordinary aluminum foil, and also has corrosion resistance and hydrophilicity that ordinary aluminum foil does not have. It is a substitute for ordinary aluminum foil used in air-conditioning heat exchangers. product. MC Aluminum can provide blue hydrophilic aluminum foil and gold hydrophilic aluminum foil.
Hydrophilic aluminum foil is hydrophilic treatment of aluminum foil. After special processing, the surface is coated with a hydrophilic layer. Condensed water will spread quickly on the hydrophilic aluminum foil and will not condense into water droplets, thus increasing heat exchange. area, speed up cooling and heating, and effectively avoid noise caused by condensed water blocking the air flow.
Hydrophilic aluminum foil usually uses alloy numbers: 1100, 1200, 8011, 1030, etc.

5 | Alkali Resistance | Dipped in 20% NaOH in 20 ºC for 3 minutes, absolutely no blister |
6 | Impregnant Resistance | Samples weight loss 1% |
7 | Heat Resistance | Under 200 ºC, for 5 minutes, performance and colour unchanged Under 300 ºC, for 5 minutes, the coating film becomes a little yellow |
8 | Oil proof | Dip in volatile oil for 24 hours, no blisters on the coating film |
9 | Odor of the coating film | No odor |
10 | Abrasion to mould | Same as ordinary aluminium foil |
Advantages of hydrophilic coated aluminum foil:1. Excellent hydrophilicity, corrosion resistance, high temperature resistance, and mildew resistance;
2. Good formability and no wear on the mold;
3. Improve heat exchange efficiency; the heat exchange rate can generally be increased by 10%-15%.
4. Easy to clean and maintain;
5. Wide range of uses, suitable for food packaging, pharmaceutical packaging, cosmetic packaging, aluminum fins and other fields;
6. Reduce vibration and noise;
7. Environmental protection;
