Modern architecture, design and creating furniture needs acrylic sheets as a result of being lightweight, clear and strong. However, acrylic can be produced in two different forms (cast and extruded); understanding these differences will help you choose the correct acrylic sheet material for your project.

CAST ACRYLIC

Cast acrylic sheets are made from liquid PMMA (polymethyl methacrylate), which is poured between two sheets of glass held apart with spacers. The two plates are then heated to a pre-set temperature and allowed to cool to create a rigid sheet.

Benefits of Cast Acrylic

  • Superior optical clarity
  • Higher hardness
  • Better chemical resistance
  • Excellent thickness consistency
  • Easier to polish and repair

Due to its high-quality surface finish and added durability, cast acrylic is usually found in higher-end applications like acrylic sheet for kitchen cabinets, designer furniture, display units and decorative features.

EXTRUDED ACRYLIC

In contrast to cast acrylic, extruded acrylic sheets are manufactured by continuously feeding molten acrylic through a die to produce sheets at a uniform thickness, much faster and cheaper than if it were cast.

Benefits of Extruded Acrylic

  • More inexpensive than cast acrylic
  • Uniform thickness
  • Easier to thermoform (heat to form)
  • Slightly lower hardness compared with cast acrylic
  • Suitable for mass production

Extruded acrylic can be used in general-purpose applications such as signage, partitions or other cost-effective ways to finish interiors.

WHICH ONE DO I USE?

When looking for an type acrylic sheet product, consider the finish of the sheet to be satisfactory, durable and resistant to wear and scratches. If your project requires an economical product or mass-produced products, extruded acrylic would work best.

Your final decision on which to use will depend on your preference for price, performance, and intended purpose. Understanding these differences will assist you in choosing the best possible acrylic product that fits your expected design and functionality, whether it is a glossy acrylic sheet or a matt acrylic sheet.
