Prime Impax 450

Prime Impax 450 is our formulated High Impact Polystyrene. It provides good toughness, stiffness and impact strength. It is designed to meet a wide variety of product applications. Prime Impax 450 is one of the most versatile and inexpensive materials we supply. It is our standard thermoforming grade of High Impact Polystyrene.

Applications:

Prime Impax 450 is FDA approved and ideal for applications such as:

  • Signs
  • Credit Cards
  • Medical Packaging
  • Building products
  • Displays
  • Furniture
  • Computer products
  • With a GP styrene cap, it is also ideal for wall surrounds, bathtubs and other interior applications such as cabinet drawer silverware holders

Processing

Since it is an amorphous thermoplastic material it is relatively easy to process in extrusion and thermoforming. The mold shrink is .003 - .006 in./in. It can be formed on aluminum, ceramic, fiberglass, epoxy and even wood tools.

Finishing

Prime Impax 450 can be fabricated by drilling, routing, sawing, die cut and/or laser cutting. Mechanical fasteners may be used as well as chemical bonding and sonic welding. We provide Prime Impax 450 in sheet or roll stock and are capable of holding extremely tight tolerances by either square cutting or slitting.

Colors, Textures and Capabilities

Prime Impax 450 can be color matched to meet your specific requirements. It is offered in thicknesses of .010 - .400 and widths of up to 120”. Textures available include; smooth, matte, Seville, RM, HC, Calf Grain, Levant, FL/HC and even flocked. Silicone coating, anti-stat, UVI and protective masking are also available.
