Bend radius acrylic sheet.

It is given by multiplying the thickness of the sheet by 100 i e. Extruded acrylic sheet will give better definition in tight radii or deep draws. Cast acrylic sheet should be heated to between 340 and 380 f 171 and 193 c.

Curved polycarbonate sheet on swimming pool enclosure in the formation of such a shape the significance of the cold forming radius comes into play. Repeat the heating process as necessary for any other bends in the sheet of acrylic.

Remember to wait until the initial bend in the acrylic has completely cooled before attempting another bend in the same sheet of acrylic. This gives the minimum radius that should be attained if the final form is to remain in place.
