What are the different types of core materials used in ACP?

Aluminum Composite Panel (ACP) is a popular material for building exteriors, interiors, and signage. The sandwich panel consists of two aluminium sheets bonded to a non-aluminium core, which provides rigidity, insulation, and lightweight properties. The core material used in ACP plays a crucial role in its overall performance and characteristics. This article will discuss the different types of core materials used in ACP.


What is ACP?


ACP is a flat panel of two thin aluminium sheets bonded to a non-aluminium core. The thickness of the aluminium sheets can vary from 0.2mm to 0.5mm, while the core material thickness can range from 2mm to 6mm. The most common ACP thickness is 4mm. ACP offers advantages over traditional building materials like masonry, wood, and steel. These include low weight, ease of installation, cost-effectiveness, weather resistance, and design versatility.


Why is Core Material Important in ACP?


The core material used in ACP significantly affects its mechanical and physical properties, such as rigidity, strength, fire resistance, and thermal insulation. The choice of core material also determines the panel's response to heat and fire. Therefore, choosing the right type of core material for your application is crucial.


Types of Core Materials Used in ACP


Polyethene (PE) Core


PE core is the most widely used core material in ACP due to its cost-effectiveness, lightweight, and ease of processing. The core material is made of low-density polyethene, which is a highly flammable material. PE core ACP is suitable for applications that do not require high fire resistance, such as signage, cladding, and interior decoration. However, it is not recommended for high-rise buildings or areas with strict fire safety regulations.


Fire Retardant (FR) Core


FR core ACP is designed to improve fire resistance and prevent the spread of fire. The core material is treated with fire-retardant additives, such as magnesium or aluminium hydroxide, to reduce flammability and smoke emission. FR core ACP is suitable for areas with strict fire safety regulations, such as hospitals, schools, and high-rise buildings.


Mineral Core


Mineral core ACP comprises non-combustible minerals, such as magnesium oxide or aluminium hydroxide, that provide excellent fire resistance and thermal insulation. The core material is bonded to the aluminium sheets using a unique adhesive that can withstand high temperatures. Mineral core ACP is ideal for applications that require high fire resistance, such as façade cladding, tunnels, and airports.


Aluminium Honeycomb Core


Aluminium honeycomb core ACP comprises hexagonal cells of aluminium foil bonded together to form a lightweight and robust core material. The core material offers excellent rigidity and compression strength while maintaining a low weight. Aluminium honeycomb core ACP is suitable for applications that require high mechanical strength, such as transportation, marine, and aerospace industries.


Polystyrene (PS) Core


Polystyrene core ACP comprises expanded polystyrene foam that offers lightweight and thermal insulation properties. The core material is bonded to the aluminium sheets using an adhesive. Polystyrene core ACP is suitable for applications that require insulation, such as cold rooms, refrigeration trucks, and sound barriers.


A2/B1 FR Core


A2/B1 FR core ACP is a new type of fire-resistant core material that complies with the European fire safety standard EN13501-1. The core material comprises non-combustible minerals, such as magnesium hydroxide and aluminium trihydroxide, that offer excellent fire resistance and smoke emission control. A2/B1 FR core ACP is suitable for high-fire resistance applications, such as high-rise buildings, hospitals, and airports.


Conclusion


The choice of core material in ACP is a crucial factor that can significantly affect the performance and safety of the final product. The core materials used in ACP are PE core, FR core, mineral core, aluminium honeycomb core, polystyrene core, and A2/B1 FR core. Each type of core material has its unique advantages and disadvantages, and the selection of suitable core material depends on the application's specific requirements.
