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
- 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)
