Cast Acrylic Sheet Thickness Tolerance

Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics.

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. Beyond 25 mm acrylite is cast to a corporate thickness specifications. These sheets vary more than any other plastic and can be 20 or more. Furthermore the ability to colour the clear mma monomer by using master batch pigments allows for.

Extruded plexiglass acrylic sheets have a higher tolerance when heated or bent and are typically more malleable than cast plexiglass acrylic sheets. 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. This material is scratch and uv resistant. Please refer to nominal and actual sheet thicknesses below.

Cast acrylic which is comparable to lucite and plexiglas acrylic is easier to machine than extruded acrylic. This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass. It stands up to outdoor use better than polycarbonate and maintains clarity over time. Exact thickness tolerances will vary by manufacturer.

What are the tolerances for plexiglas g acrylic sheet thickness length and width flatness. Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness. Preshrunk sheet sheet that is thermally preshrunk but does not meet mil p 5425. Available in thicknesses of 060 to 4 250.

Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. Textured sheet sheet is available with a matte gl 15 finish in clear and colors. Thickness tolerances for acrylic sheet here are the tolerances on the thickness of the acrylic sheets that we offer. 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.

These are general guidelines for thickness tolerances on plexiglass acrylic sheets. As manufactured the flatness tolerance of plexiglas g sheet depends on the long dimension. As an example cast acrylic sheet is poured between 2 sheets of glass. Iso 7823 1 provides thickness tolerances up to 25 mm.

Cast clear acrylic sheet thickness tolerances are 10 and can vary throughout the sheet but variations are typically less than 5.
