Thickness tolerance of ACRYLITE® cast sheet

Having a tight thickness tolerance is important for several reasons. When dealing with a transparent material, larger variations in thickness can cause visible distortions and inconsistences that can hinder the aesthetic appeal of displays and signage. Having varying thicknesses in a single sheet also affects how much light is emitted through. For example: An inconsistent thickness would make a LED sign appear cheap or “dirty”. Consistency in sheet thickness facilitates ease of use by providing a predictable and expected outcome.

ACRYLITE® cast acrylic sheet is manufactured according to ISO 7823-1, Plastics―Poly(methyl methacrylate) sheets―Types, dimensions and characteristics. ISO 7823-1 provides thickness tolerances up to 25 mm. Beyond 25 mm, ACRYLITE® is cast to a corporate thickness specification. The table below covers a range of standard thicknesses we produce, from 3 mm to 150 mm. Tolerances also apply both to smooth and velvet texture ACRYLITE® Satinice cast products.
