A2 Fire Resistant Aluminum Composite Panel, ACP Panel
Aluwedo® A2 fireproof Aluminum magnesium composite panel (AMCP) is made from one layer of natural inorganic mineral material core and two layers of anti-scratch high-strength aluminum plates, between the 2 of which there is a special adhesive film, manufactured by constantly solidified and laminated under high temperature. The middle core is natural inorganic mineral materials, such as magnesium hydroxide, aluminum hydroxide, talcum powder, and light calcium carbonate, etc. All of them are green flame-retardant inorganic materials with multi-function of retarding, and suppressing smoke. For example, Magnesium Hydroxide - (Mg(OH)2), will decompose to absorb the caloric of burning articles only when the temperature reaches 340~490℃.
