Aluminum composite panel is made of multi-layer material. While the upper and lower layer is high purity aluminum alloy panel, the middle is non-toxic low density polyethylene (PE) core panel. And its front side is also covered with a protective film. For exterior applications, the front side of the aluminum composite panel is coated with fluorocarbon resin (PVDF), while for interior applications, the front side can be coated with polyester (PE). There are wide ranges of color options, and the construction methods are easy with the panels’ excellent processing properties.
