High Impact Polystyrene

ACI HIPS high impact clear polystyrene plastic is a low cost, tough plastic material that is easy to thermoform and fabricate. It is often used for retail display, countertop point-of-puchase (POP) displays, banners, and indoor signs.

High impact polystyrene can be assembled with mechanical fasteners, solvents, or adhesives.

Printable grades of polystyrene can be decorated using a variety of printing methods including:

  • Screen-printing
  • Offset lithography
  • Flexography



Polystyrene is one of the most widely used kinds of plastic. Pure solid polystyrene is a colorless, hard plastic with limited flexibility.  More than half of all polystyrene produced is blended with 5 to 10 percent polybutadiene to reduce brittleness and improve impact strength. This blend is marketed as high-impact polystyrene or HIPS for short.

Several other copolymers are also used with styrene. Acrylonitrile butadiene styrene (or ABS plastic) is similar to HIPS: a copolymer of acrylonitrile and styrene, toughened with polybutadiene.
