Extrusion is a continuous manufacturing production method where PMMA granular is first heated then fed through barrels where the physical process occurs. As a result, extruded acrylic is heterogeneous with properties that may vary depending upon the direction of extrusion.

Extruded acrylic costs less than CAST and is more dimensionally stable, meaning the thickness is more consistent across sheets. Softer, with a lower melting temperature than in its cast form, extruded acrylic is easier to laser cut, rout, and polishes more cost-effectively.

Extruded acrylic is less susceptible to dirt, lint, or particulate contamination in the production process. Additionally, because of its lower melting point, it is better suited to cementing and thermoforming.

Both Cast and extruded can be polished, it is more durable option for multiple applications.

Extrusion process

  • Extrusion temperature : 180-250°C
  • A degassing screw with an L/D ratio of 20-30 is recommended
