Extruded Acrylic is a low molecular weight polymethyl methacrylate, made by melting acrylic polymer granules and extruding the melt into sheets.

Extruded Acrylic properties are similar to Cast Acrylic, but due to its lower molecular weight, has lower crazing, chemical, and solvent resistance, but provides better vacuum forming definition. It is available in a limited range of colours and thicknesses, and in UHI impact modified variants.
