Acrylonitrile-butadiene-styrene + Polycarbonate (ASA+PC)

Alternative and trade names
Geloy, Luran®


PC/ASA blends provide very good UV-Stability and surface properties. They are widely used for exterior parts in automotive applications. This material can be used to avoid the painting process. PC/ASA blends can be used in injection molding including flame retardant applications. Benefits and features:

  • High gloss and matte surfaces
  • High temperature stability
  • Excellent UV stability and high Impact strength at low temperatures
