Product Description
Non-combustible A2 Aluminum composite panel is a composite panel composed of two aluminium sheets and a mineral core developed to meet the highest standards of fire classification.
For A2 class fireproof aluminum composite panel, it Contains 93% of the flame retardant,the main ingredients are aluminium hydroxide (Al(OH)3) and magnesium hydroxide (Mg(OH)2); it can be catched on fire after 20 minutes, and the fire will extinguish at once when the fire leave the panels.
Thanks to its exceptional mechanical properties: high rigidity, excellent flatness, impact resistance, durability and ease of maintenance, together with a A2-S1, d0 fire rating (according to EN 13501:2018), the A2 Fire proof Aluminum composite panel is the ideal cladding solution for high-rise and high-occupancy buildings.
