Working with ACRYLITE®

Minimum cold formed radius

Product Cold-bending radius
ACRYLITE® extruded acrylic sheet
ACRYLITE® Optical mar-resistant sheet		 330 times the thickness
ACRYLITE® cast acrylic sheet 330 times the thickness
ACRYLITE® LED sign grade acrylic sheet 240 times the thickness
ACRYLITE® Resist 65 acrylic sheet 240 times the thickness
ACRYLITE Resist 45 sheet 330 times the thickness

The minimum (i.e., tightest) radius to which this product can be cold formed is equal to the above value multiplied by the thickness of the sheet. Calculated below is the minimum cold forming radius for an ACRYLITE® extruded sheet with various thicknesses.

0.177”: Minimum Radius = 330 x 0.177 = 58.41 inches
0.236”: Minimum Radius = 330 x 0.236 = 77.88 inches
0.375”: Minimum Radius = 330 x 0.375 = 123.75 inches
0.500”: Minimum Radius = 330 x 0.500 = 165.00 inches

The practice of cold forming a sheet of material tighter than its recommended minimum radius is likely to result in cracking or crazing of the sheet, sometimes upon installation but most often after an extended period of time in service (months or years).
