| WELLBOND® ALUMNUM COMPOSITE
PANEL: |
DIMENSIONS:
· Thickness: 1.5-8mm
· Width: <1570mm
· Length: <7000mm
· Aluminum thickness: 0.10mm-0.50mm
Product Tolerance:
Length: -0 + .375”
Width: -0 + .188”
Thickness: ± .008” for 3 to 6mm thicknesses
Bow (length and/or width): Maximum 0.8%
Squareness: Maximum .250”
Minimum Bending Radius:
The minimum bending radius of WELLBOND® Material without cutting an
aluminum sheet is 15 times the thickness of the WELLBOND® Material.
Bond Integrity:
WELLBOND® Material has been tested to ASTM D-1781-93 for bond integrity,
simulating its resistance to delamination.
The following values have been established: Peel Strength - 115 Nmm/mm
(Minimum)
No appreciable loss of bond strength has been determined due to normal
weather conditions.
Temperature Resistance:
Withstands environmental temperature changes from -55°F to +175°F.
The coefficient
of linear expansion is governed by the aluminum sheet. |
