Acrylic (Perspex, Plexiglas) PMMA Sheet


PMMA, also known as Acrylic glass or Acrylic is a transparent thermoplastic; it is often seen in sheets and used as a shatter resistant light-weight alternative to glass. Acrylic is a much cheaper alternative to Polycarbonate, especially when impact strength or hear/ chemical resistance isn’t as important as UV tolerance, transparency, tensile or flexural strength. Acrylic is also often preferred because of its easy handling, processing and the low cost of the plastic. Non modified Acrylic can be brittle under heavy loads and impact force; it’s also more likely to scratch that normal glass and is often protected by a film until installed. Modified Acrylics on the other hand are sometimes able to achieve high impact and scratch resistance.

Acrylic can be produced in 2 basic ways, extruded and cast. Extruded Acrylic is often a go to material for a number of applications in the fabrication and signs industry and due to the ease of working with the plastic. Cast Acrylic has a lower melting point than extruded Acrylic meaning it’s is always softer this makes it easier to laser and polish giving a much nicer finish to the more popular applications like the display industry. Whereas cast acrylic is preferred for machining due to its greater range of thicknesses and lower water absorption. Cast acrylic also offers a higher rigidity and resistance to electricity and weathering.
