ASA

ASA is often called “ABS for outdoor use”

Why choose it?

  • You want a material with mostly the same properties as with ABS but with better UV resistance. On medical products, ASA is a common choice since the products need to be clear white and remain that way.

Why not choose it?

  • Poor chemical resistance
  • Prone to environmental stress cracking (a reason not to use ASA on medical products)

Typical applications:

  • Surfaces of medical products that should keep their white color. (If the product is often wiped with strong detergents, PBT is a safer choice)
  • Component of a garden watering system (questionable if a good choice)
