Aluminum composite sheet Fireproof – Premium bond

Aluminum composite sheet Fireproof – WHAT YOU NEED TO KNOW?

Why use premium fireproof composite (FR) aluminum composite sheets?

Most sheets are made of two layers of 0.5 mm aluminum and 3 mm polyethylene.
This means that 75% of the sheet consists of polyethylene.

At temperatures above 100. C, polyethylene begins to soften, shrink, and eventually melt.

During the melting stage, toxic flammable gases are released.

At temperatures above 350. C, they become flammable gases

And at temperatures between 450 and 500 degrees Celsius, these gases ignite.

In parallel with this process, the polyethylene core loses its strength and the outer aluminum layer separates while the polyethylene is still adhering to it, and is more flammable since it is exposed to more open air. Be.

Aluminum sheets with different alloys have different melting points:

EN AW 1050 646-657 ° C

EN AW 5754 610-640 ° C

EN AW 6060 585-640 ° C

1kg of polyethylene produces 2,300 cubic meters of highly toxic gases, including carbon monoxide, cyanide, carbon dioxide and soot.

Aluminum fire-retardant composite sheets, or so-called slow-burning (FR), are more resistant to fire than Grid B1, slowing down the process of fire and thus providing more protection to people inside the building.

This material has the property of stability against variable weather conditions and excellent performance

And not only does it eliminate the problem of non-fireproof aluminum composite sheets

Rather, it dramatically improves the dynamic performance of the bending or folding parts of the panel, which is the weakest part of an aluminum composite panel.

Both surfaces are coated with different degrees of baking by the Coil coating method.

The grade of this material, which consists of oxygen, unnatural fine materials and many types of materials with high molecular density, is very high.

Aluminum composite sheets are bonded at high temperatures with high-performance molecular hardeners.

To reach the highest level of stability against scaling.
