Aluminum Composite Panel (ACP), also referred to has Aluminum Composite Material (ACM), is a type of flat panel that consists of two thin aluminum sheets bonded to a non-aluminum core. ACP’s are frequently used for external cladding or facades of buildings, insulation and signage.
Aluminum sheets can be coated with polyvinylidene fluoride (PVDF), fluoropolymer resins (FEVE), or polyester paint. Aluminum can be painted in any kind of color, and ACP’s are produced in a wide range of metallic and non-metallic colors as well as patterns that imitate other materials, such as wood or marble. The core is commonly low density polyethylene, or a mix of low density polyethylene and mineral material to exhibit fire retardant properties.
Sandwich panels are used in those applications where high structural rigidity and low weight is required. An evident example of use of sandwich panels is an aircraft where mechanical performance and weight saving is essential. Other applications include packaging (e.g. fluted polypropylene boards of polypropylene honeycomb boards), transportation and automotive as well as building & construction.
Aluminum Composite Panel (ACP) is mainly used for external and internal architectural cladding or partitions, false ceilings, signage, machine coverings, container construction etc. Applications of ACP are not limited to external building cladding, but can also be used in any form of cladding such as partitions, false ceilings etc. ACP is also widely used within the signage industry as an alternative to heavier, more expensive substrates.
ACP has been used as a light-weight but very sturdy material in construction, particularly for transient structures like trade show booths and similar temporary elements. It has recently also been adopted as a backing material for mounting fine art photography, often with an acrylic finish using processes like Diasec or other face-mounting techniques. ACP material has been used in famous structures as Spaceship Earth, VanDusen Botanical Garden, the Leipzig branch of the German National Library.
These structures made optimal use of ACP through its cost, durability and efficiency. Its flexibility, low weight and easy forming and processing allow for innovative design with increased rigidity and durability.
