What Is the Aluminium Composite Panel？

Based on historical standards and industry sources, an Aluminium Composite Panel (ACP) is a versatile building material defined as follows:

1.Core Structure & Composition

Sandwich Design: ACP consists of three bonded layers:

Two outer skins: Rolled aluminium sheets (typically 0.1–0.5mm thick).

Core layer: Polyethylene (PE) plastic or fire-retardant mineral-filled core (e.g., magnesium hydroxide).

Bonding: High-strength adhesive films (e.g., polymer-based) fuse layers under heat/pressure .

Standard Thickness: Total panel thickness ranges from 3mm to 6mm, though specialty panels (e.g., for industrial use) can reach 20mm .

2. Key Properties

Lightweight: 5–7 kg/m² (vs. solid aluminium panel, 12+ kg/m²), easing installation.

Rigidity: High bending strength due to composite effect (core resists shear stress)

Weather Resistance: UV-resistant coatings (e.g., PVDF, polyester) prevent fading/corrosion.

3. Primary Applications

Building Cladding: Curtain walls, rainscreen systems

Signage & Displays: Smooth surface ideal for digital printing (advertising boards, exhibits) .

Transport & Interior: Caravan sidings, partition walls, furniture .

4. Safety Considerations

Fire Risk: Standard PE cores are flammable; B1-grade mineral cores are mandatory for high-rises in many countries . Violations can cause fires.

Certifications: Look for EN 13501-1 (EU), NFPA 285 (US), or GB/T 17748-2016 (China) compliance .

5. Summary

ACP is a lightweight, formable cladding solution combining aluminium’s durability with plastic’s flexibility. Critical to prioritize fire-safe cores (mineral-filled) and certified coatings for architectural use. For detailed technical specs, consult or manufacturer test reports .
