Polyketone

Polyketone (PK) Materials

Polyketone (PK) is a high-performance engineering thermoplastic known for its exceptional chemical resistance, mechanical strength, resiliency, and low moisture absorption. This semi-crystalline polymer is ideal for applications demanding durability, toughness, impact resistance, fatigue resistance, low friction, and abrasive wear resistance, making it a preferred choice for various end use markets.

Characteristics and Properties

  • Outstanding chemical resistance, especially to hydrocarbons and solvents
  • High mechanical strength and toughness
  • Excellent abrasive wear resistance and low friction
  • Low moisture absorption
  • Dimensional stability
  • Superior impact resistance
  • High crystallinity resulting in shorter cycle times
  • Good processability in injection molding and extrusion with no off-gassing

Applications

  • Agriculture (irrigation components, fruit sorters, tractor components)
  • Automotive components (fuel system parts, bushings)
  • Consumer goods (sports equipment, power tools, toys, gun components, cosmetics)
  • Industrial (valves, seals, gears, bearings, clips, living hinges, fasteners)
  • Electrical and electronics (connectors, insulators, housings)
  • Medical devices (instrument components, housings)
