Acrylic Machining

A Guide to Acrylic CNC Machined Parts: Properties, Applications and Design Considerations

What is Acrylic?

Acrylic, commonly known as the brand name Perspex®, is a transparent thermoplastic with excellent strength and optical clarity and is thus widely used as a glass substitute; though it outperforms glass in several aspects.

Similar in characteristics to Polycarbonate, Acrylic has a lower impact strength but still boasts 10-24 times the impact resistance of glass. It is also more flexible and lighter than glass.

Main Attributes of Acrylic:

  • Excellent optical clarity and light transmission properties
  • Abrasive resistance comparable to aluminium
  • Good chemical resistance
  • Good flexural strength
  • Around half the weight of glass and easier to process
  • Readily available and reasonability cost effective
  • Excellent weatherability and resistance to sunlight
  • Excellent dimensional stability
  • Subject to stress cracking
  • Combustible
  • Available in transparent or opaque forms
  • More flexible and shock resistant than glass
  • Good insulator
  • Good acoustic properties (can act as sound barrier)
  • BPA free
  • Easy to solvent bond
  • UV resistant
  • FDA Compliant grades available
  • Available in all colours imaginable
  • 100% recyclable
  • Available with a range of coatings including abrasion resistant, bullet resistant and electrostatic dissipative (ESD)
