ASA

Also known as: ASA Filament, Acrylonitrile Styrene Acrylate

intermediate Materials

A UV-resistant alternative to ABS, ideal for outdoor applications.

ASA (Acrylonitrile Styrene Acrylate) is similar to ABS but with excellent UV resistance, making it ideal for outdoor applications.

Properties

  • UV stable - Won’t yellow or degrade in sunlight
  • Heat resistant - Similar to ABS
  • Good strength - Impact and tensile
  • Chemical resistant
  • Paintable
