High Impact Polystyrene (HIPS) is a versatile, economical and impact-resistant plastic that is easy to machine and fabricate. HIPS is often specified for low strength structural applications when impact resistance, machinability, and low cost are required. It is frequently used machining pre-production prototypes since it has excellent dimensional stability and is easy to fabricate paint and glue.

Common Uses:

  • Consumer products: Appliance components, toy, TV and audio-visual equipment parts, recording tape cassettes, bicycle trailer, toys
  • Automotive industry: Instrument panels and fittings, gasoline tanks
  • Food Services: Hot and cold drinking cups
  • Office Products: Computer Housings

Physical Properties:

  • Specific Gravity – 1.04g/cm
  • Tensile Strength – 3130 psi
  • Flexural Strength – 4620 psi
  • Impact Strength – 2.20ft.-lb/in

General Properties:

  • Maintains strength in high-impact applications
  • Can be painted
  • Recyclable with good property retention
  • Easily moldable
  • FDA compliant grades
  • Good dimensional stability
  • Good gloss
  • Low volatility

Processing:

  • Injection Molding
  • Extrusion
