As a dark horse in the building materials industry, aluminium composite panel is increasingly favored by consumers due to its diverse varieties and extensive use. In this post, I will introduce a kind of fireproof wall panels, which is aluminum composite panel. I hope this post can give you some advice if you have the requirement of acm fire protection.

Brief description of fire rated aluminium composite panel: 

fire rated acpFire rated aluminum composite panel refers to that aluminium composite panel is adopted flame-retardant core material, and the combustion performance of the product reaches the refractory grade (class B1) or non-combustible grade (class A); At the same time, other performance indicators must also meet the technical specifications of aluminum composite panels.


The difference between B1 grade and A2 grade fire resistant aluminum composite panels

1.The ingredients of fire core materials are different:

For B1 grade plastic core, it contains: 55% - 55% flame retardant, the main ingredients are aluminum oxide (Al₂O₃) and magnesium oxide (MgO) ;

A2 grade fireproof aluminium composite sheet plastic core material : It Contains 88% - 90% of the flame retardant, the main ingredients are aluminium hydroxide(Al(OH)3) and magnesium hydroxide (Mg(OH)2) ;

2.Different reactions to fire:

For B1 grade fireproof aluminum composite sheet:

When B1 grade panels are put on fire, it can be catched on fire after 5 minutes, and the fire will extinguish after 10 seconds when the fire leave the panels.

A2 grade fireproof aluminium composite sheet:

it can be catched on fire after 20 minutes, and the fire will extinguish immediately when the fire leave the panels.

3.Different testing indicators and requirements:
Testing indicators and requirements of B1 grade fireproof aluminium composite boards:

(1) According to GB/T8625-88 test, the average residual length of each set of specimens ≥ 150mm, (the remaining length of each specimen> 0), and the average peak temperature of each test flue gas temperature ≤ 200 °C;

(2) According to GB/T 8626-88 test, height index of flame tip <150mm, and the phenomenon of ignition of filter paper by burning drips is not allowed;

(3) According to GB/T8627-1999 test, smoke density rating (SDR) ≤ 75.

Testing indicators and requirements of A2 grade fireproof aluminum composite board:

(1)According to GB/T 8625-88 test , the average residual length of each set of specimens ≥ 350mm (the remaining length of any specimen is > 200mm), and the peak value of the average flue gas temperature for each test ≤ 125°  No burning phenomenon on the back of the specimen;

(2)According to GB/T8627-1999 test, smoke density rating (SDR) ≤ 15;

(3) According to GB/T14402-93 and GB/T14403-93 test, the thermal value of its material ≤ 4.2MJ/kg, the heat released per unit area of the test piece ≤ 16.8MJ/m2;

(4)According to GA 132--1996, the total non-lethal concentration of Lco in flue gas toxicity of burning materials is greater than or equal to 25.0 mg/L, and the mice will not die within 3 days after exposure and their weight will be recovered.

The application of B1 grade fireproof aluminum plastic board and A2 grade fireproof aluminum plastic plate

B1 grade fireproof aluminium composite plate:

Although not strictly referred to as Non-combustible ,it has a very low spread of flame indices and will not contribute to the spread of flame. Therefore, this type of panel may be used on high rise buildings. It must be attached to a fire rated wall.

A2 grade fire retardant aluminium composite panel:

This type of panel is Non-combustible, which may be used on high rise buildings. It must be attached to a fire rated wall.
