B1 Fire-resistant Aluminium Composite Panel
Core Structure and Fire-Resistant Composition of Alucobang B1 ACP
Alucobang B1 FR aluminum composite panel is composed of two aluminum sheets sandwiching a mineral core. The middle layer is made of non-combustible mineral material, This core is modified by adding halogen-free and environment-friendly flame retardants. It appears as off-white or white solid granules, with both environmental protection and fire resistance properties. This mineral material also endows the aluminum-plastic composite panel with high peel strength and outstanding impact resistance.

Fire Performance
In Aluminum Composite Panel, core material plays a major role in determining the fire property of the building. Its fire performance is classified into four flame-retardant grades: B1+, FR, HFR, and A2. Tested by authoritative institutions such as SGS and INTERTEK, the panel meets the following standards respectively:
| Core Material Classification | Non-FR PE | FR B1 | FR | HFR | FR A2 |
|---|---|---|---|---|---|
| Proportion of Flammable Components in the Core Layer |
100% | < 50% | < 35% | < 28% | < 10% |
| Core Layer Calorific Value | > 45 MJ/kg | < 22 MJ/kg | < 15 MJ/kg | < 15 MJ/kg | < 3 MJ/kg |
| Oxygen Index | 16-18 | 28-30 | 32-34 | ≥80 | ≥80 |

Key Features of Alucobang B1 Fire-Resistant Aluminium Composite Panel
Designed for safety, durability, and performance — fire-resistant, eco-friendly, and long-lasting.
Superior Fire Protection
Meets B1-class flame-retardant standards, resists ignition and self-extinguishes quickly to prevent fire spread.
Superior Fire Protection
Meets B1-class flame-retardant standards, resists ignition and self-extinguishes quickly to prevent fire spread.
Eco-Friendly & Safe Core
Halogen-free, low-smoke, non-toxic mineral core — compliant with green building standards.
Strong Bonding & Impact Resistance
Exceptional adhesion between layers ensures durability and resistance to bending or external stress.
Good Weather Resistance and Durability
The surface mostly uses PVDF coating, which provides excellent resistance to sunlight, rain, wind, and snow. It also offers superior corrosion resistance and pollution resistance, ensuring long-lasting color stability and durability even in harsh outdoor environments.
Ordinary PE Aluminum Composite Panel
It burns easily, and the flame continues to burn after the fire is turned off.
Class B1 Fire- Resistance Aluminum Composite Panel
There are faint sparks, the flame stays on the surface, the flame slowly extinguishes after the fire is turned off, there is residual ash on the surface, and there is no obvious sign of collapse in the internal structure.
Class A2 Fire- Resistance Aluminum Composite Panel
No signs of combustion, no obvious burning signs, and the internal structure remains intact.
Application of Class B1 Fire-Resistance Aluminum Composite Panel
Ideal for eco-safe interior architectural spaces: malls, metro corridors, hospitals, offices and residential façades.
