Acrylonitrile styrene acrylate (ASA)

Short description: ASA is a thermoplastic polymer that is similar to ABS but has improved weather resistance. It is known for its UV resistance and high mechanical strength, making it ideal for outdoor use. ASA offers a good surface quality and is relatively easy to print.

Suitable uses:

  • Outdoor applications (e.g. automotive parts, garden tools)
  • Functional parts that have to withstand the effects of the weather
  • Enclosures and components for maritime use

Unsuitable uses:

  • Objects that come into contact with food (not food-safe)
  • Applications that require a very high degree of flexibility
