CYREX 200-8000 alloy is an opaque, acrylicpolycarbonate alloy with an impact strength that is higher than polycarbonate.

Typical properties of CYREX® acrylic-polycarbonate alloys are:
  • outstanding impact strength and toughness
  • excellent processing characteristics
  • very good chemical resistance
  • good heat resistance

The special property of CYREX 200-8000 alloy is:
  • medium melt flow rate

Used for injection molding and extrusion of both thin and thick wall applications which require excellent toughness.
