Fire Performance Comparison of Alucobang Aluminium Composite Panels
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
| 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 | |

Comparison of Fire Resistance Tests
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.
Key Features of Alucobang HFR High Flame-Retardant Aluminium Composite Panel
Engineered for enhanced fire resistance, environmental safety, and superior surface durability — ideal for projects demanding both advanced protection and modern architectural appeal.
HFR-Level High Flame Retardancy
