Cast Acrylic Sheet Thickness Tolerance

These cast acrylic sheets bars and cubes are often fabricated into tanks see through barrier panels and light fixture lenses.

Cast acrylic sheet thickness tolerance.

These are general guidelines for thickness tolerances on plexiglass acrylic sheets. Available in thicknesses of 060 to 4 250. As an example cast acrylic sheet is poured between 2 sheets of glass. It generally is the best thickness consistency softest sheet easy to glue best for chemical bonding and the standard material for displays replacement windows and some signage applications.

Please refer to nominal and actual sheet thicknesses below. Exact thickness tolerances will vary by manufacturer. Preshrunk sheet sheet that is thermally preshrunk but does not meet mil p 5425. It stands up to outdoor use better than polycarbonate and maintains clarity over time.

Cast acrylic which is comparable to lucite and plexiglas acrylic is easier to machine than extruded acrylic. Beyond 25 mm acrylite is cast to a corporate thickness specifications. This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass. Cast clear acrylic sheet thickness tolerances are 10 and can vary throughout the sheet but variations are typically less than 5.

This allowance is based on astm d 4802 section 5 6 1. Iso 7823 1 provides thickness tolerances up to 25 mm. Textured sheet sheet is available with a matte gl 15 finish in clear and colors. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics.

Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness. Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. These sheets vary more than any other plastic and can be 20 or more. Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet.

This would mean a 1 00 thick sheet could be from 80 1 20 thick within the same sheet and still be within the factory tolerance materials within a factory tolerance can not be returned. Furthermore the ability to colour the clear mma monomer by using master batch pigments allows for. What are the tolerances for plexiglas g acrylic sheet thickness length and width flatness. Extruded plexiglass acrylic sheets have a higher tolerance when heated or bent and are typically more malleable than cast plexiglass acrylic sheets.

Thickness tolerances for acrylic sheet here are the tolerances on the thickness of the acrylic sheets that we offer.
