Fire rated aluminium 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.
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 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 panels: 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. While for A2 grade fire rated aluminium composite panels, 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 aluminium composite panel:
(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.
Buildings are always at risk of catching fire due to short-circuiting or other issues. You need to ascertain that the materials used for the construction of the building are the best and if possible, fire retardant. The ACP sheets, used for the interiors and exteriors of the building are fire retardant.
These sheets cut the following three elements needed for the ignition and combustion in any place:
· Fuel to burn
· Air for oxygen supply
· High ignition temperature that continues the combustion
As the aluminium composite panels are thermal resistant, they do not conduct the heat very quickly. This makes them a barrier against fire. In addition, the fire retardant cores that these sheets have, make them fire-proof.
In the absence of the required elements of combustion, the fire does not spread very fast. They can contain the fire for up to 2 hours, which is a crucial time that can be utilized to save lives and property.
You can look for the ideal aluminium sheets with your dealer and get the ACP sheet price. The cost of the panels would depend upon the design and colour that you choose and on whether you choose a normal panel or a fire retardant one. If you have any need, please do not hesitate to contact us!
