Technology Data Sky Rainbow

SUMMARY OF SPECIFICATION DATA1. GeneralSKYRAINBOW is an Aluminium composite panel (ACP ) with nontoxic filled core, used as an exterior and interior cladding and roof covering on the new building and retrofit applications. The material is manufactured by Jiangyin Tianhong Decoration Material Co., Ltd. And furnished by approved agent or distributors.

2. Product Composition

The aluminium composite panel (ACP) should be composed of thermoplastic core of low density polyyethylene sandwiched between two aluminium sheets. The frontal surface is finished with a high performance Lumiflon-based fluorocarbon coating (as standard ) or polyestercoating, and the back side is a wash coating or primer coating. SKYRAINBOW is available on the following finishes: Solid colors, Metallic colrs, Brushed colors, Mirror colors, Pearlescent colors (95% high gloss), granite colors. All these finishes are applied in munufacturers coutinuous coil coating lines. The surface is protected with a self-adhesive peel off protevtive film to avoid any nicks or other damages, which should be peel off immediately after installation.

8. Vibration DampingAs a laminated composite panel , skurainbow can damp the vibration velocity and amplitude by absorbing or conventing vibration energy into thermal energy. Tested sampls size: 20mm x 300 mm


Deflection by wind load is changing as the panel thickness, aspect ratio, span and boundary condition i.e. simply supported or finxed. The aspect ratio is ratio the longer to the shorter dimension of the panel. Deflections differ between panels of the same area but od different aspect ratio. For example, deflection of dimension 600mm x 2400mm ( aspect ratio is 4 ) panel is smaller than the size of 1200mm x 1200mm ( aspect ratio is 1 ) The following 3 illustrations show the really measurement of fixed SKYRAINBOW ACP deflections.
