About Polyketone (POK)

Aliphatic polyketone is a newer semi-crystalline engineering resin. Molders reach for it when acetal parts wear or squeak, or when nylon parts swell and lose dimension from moisture. It stands up to fuels, oils and many solvents, stays tough when wet, and runs on standard injection equipment. It is not a high-heat material: it melts around 220°C and is best below roughly 100°C continuous. Above that, look at PEEK.

Sourcing note: we supply polyketone through import channels. If you need domestic-only material, tell us in the form and we’ll let you know what’s possible before quoting.

Grades we source

  • Unfilled injection grades
  • Glass-filled (15–30%)
  • Carbon-fiber filled (wear & static control)

  • Food-contact grades

Common applications

  • Gears, bushings and bearings
  • Wear strips, slides and guides
  • Fuel-system and under-hood parts
  • Water-meter and plumbing components
  • Connectors, clips and fasteners
