PLEXIGLAS® SHEET: COLD FORMING
Plexiglas® sheet can be cold formed (bent at room temperature) in a smooth arc and held to a radius by forcing the material into a curved channel support. The recommended radius of curvature should be a value greater than 180 times the thickness of the sheet for Plexiglas® G sheet, and 300 times the thickness for Plexiglas® MC sheet (See table below).
Recommended Minimum Radii of Curvature for Cold-formed Plexiglas® Sheet
Nominal sheet thickness Recommended minimum radius (in)
Radii of curvature less than those specified may exceed the design stress limits for the material, resulting in crazing.
NA = Not Applicable.
