Why choose PPS?

  • Excellent chemical resistance
  • Good dimensional stability
  • Essentially zero moisture absorption
  • Machines to tight tolerance

What are some common PPS applications?

  • Bearings
  • Rings
  • Rotors
  • Steam or water applications

PPS is a high-performance thermoplastic ideal for applications requiring chemical resistance and mechanical strength at high temperatures (up to 425°F). In addition to its other properties, PPS offers virtually zero moisture absorption, good dimensional stability, and excellent electrical properties - making it a strong choice for extreme operating conditions. PPS comes in a variety of stock shapes, and colors range from opaque white to light tan.
