ASA is an amorphous thermoplastic with a glass transition temperature of 100 C. ASA offers a combination of mechanical and chemical properties at a low cost. ASA has better UV resistance than ABS. But the impact resistance is lower in the cold than ABS.

ASA Properties

  • Good mechanical strength and chemical resistance, but not against solvents
  • High impact strength, surface hardness and surface finish
  • Very good color resistance
  • Good outdoor resistance and dimensional stability
