Sandwich ACP Panel

ACP (Aluminium Composite Panel), often known as sandwich panel, is one such structure or material. This material is used in the majority of passenger and cargo aircraft, ensuring mechanical performance and lighter weight.

Aluminium composite panels (ACPs) are panels that are constructed of an aluminium composite material that consists of a thermoplastic polyethylene core or a fire retardant core sandwiched between thin aluminium sheets.

However, it should be noted that polyethylene is not a fire-resistant material. In fact, it catches fire and spreads.

As a result, while purchasing sandwich ACP panels, ensure that the inside material is polyethylene or not to avoid future risks.

ACP is most commonly used for exterior and interior architectural cladding or walls, artificial ceilings, signs, machine coverings, container construction, and other related purposes. These panels are also used in construction projects of type C. For the uninitiated, class C constructions are the least fire-resistant and often consist of one to two-story buildings.

Several studies have revealed that the sandwich ACP panel with polyethylene core quickly catches fire. In fact, several countries, including the United Arab Emirates, have prohibited ACP panels. However, you should be aware that no ACP panel is fireproof; they are simply fire code compliant.

Since aluminium has a low melting point–around 660 ° C, it will melt immediately in the case of a fire. To make aluminium sheets fire-resistant, they are coated with polyvinylidene fluoride (PVDF) or polyester paint.
