I need to find a suitable grade of a polyurethane material for a crictical application where in i need to roll a sheet of polyurethane like rolling a piece of paper...with out breaking or permanently deforming the sheet ....

Pi D of the sheet is 82 mm , length 40 mm and thickness 1 mm
which i need to roll it to final diameter of 7 mm (cylinder dia)

since the force i need to apply for rolling the sheet is unknown im unable to freeze on the material properties like E,compressive strength etc ....

any suggestions for choosing the right grade with adequate flexibility .............
