A sheet made of aluminium and plastic,Aluminum and plastic core material under certain conditions ,The plate formed by special adhesive bonding composite.The actual production is generally used as a positive,Back aluminum coating,And then compounded with the plastic core material,

The thickness of the aluminum and the thickness of the plastic core is the thickness of the plate 2MM~8MM.More commonly used at home and abroad 3MM, 4MM; foreign also need 5MM, 6MM board,It can also produce 8MM thick aluminum plate. 2MM is relatively small, the manufacturers are relatively small,almost no interests,

Thickness of aluminum skin between 0.06~0.5MM,More common 0.15MM ,0.21MM,0.3MM,0.4MM,0.5MM .

The thickness of the core material depends on the thickness of the plate and aluminum thickness adjustment in production
