EnduraPanel has excellent flexibility:
6mm sheet can be cold-bent to a recommended minimum radius of 1.5M
4mm sheet can be cold-bent to a minimum radius of 0.8M
EnduraPanel can be bent using heat to a minimum radius of 5mm.
This is however a specialised process and should only be attempted by an experienced acrylic thermoformer or acrylic fabricator.
As with all acrylic sheet products, the bending process actually modifies the structure of the material and as such will void warranty.
