Signature Plastics

PS (Polystyrene)

Signature Plastics extrudes custom PS (Polystyrene) profiles for applications where rigidity, clean detail, and visual appearance are important. PS is commonly selected when a profile needs to hold sharp edges, maintain precise geometry, and present a clean, finished look.

PS (Polystyrene) extrusions are typically used in interior, low-impact environments where profiles are not subjected to heavy loads, repeated flexing, or harsh exposure.

What is PS (Polystyrene)?

Polystyrene is a rigid thermoplastic material known for its stiffness and ability to reproduce fine detail. In extrusion, PS is used for profiles that require crisp edges, consistent wall thickness, and a smooth surface suitable for visible applications. PS is not used where impact resistance, flexibility, or outdoor durability are required. It is chosen when appearance and shape definition take priority.

Typical PS Applications

PS is commonly specified for extruded profiles used in interior and display-focused applications. Applications include:

  • Display and point-of-purchase profiles
  • Decorative trim and molding
  • Signage and graphic frames
  • Light-duty interior profiles
  • Covers and housings in protected environments
  • Retail fixture profiles
  • Architectural detailing profiles

Many PS profiles are cut, mitered, or assembled after extrusion to meet installation or layout requirements.

Advantages of Extruded PS (Polystyrene)

  • Rigid material with good shape definition
  • Produces sharp edges and fine detail
  • Smooth surface finish suitable for visible use
  • Lightweight compared to many rigid plastics
  • Cost-effective for interior and decorative profiles
  • Easy to cut and fabricate

PS is typically selected when a profile needs to look clean, hold precise detail, and remain rigid in a controlled environment, rather than absorb impact, flex, or seal.
